#61: What's Happening: Divers, and Costumes, and Pumpkins, Oh My!

On October 23rd the Giant Ocean Tank (GOT) staff and volunteers took part in our annual event called "Fish, Fun, and Fright." (See photos and videos from last year's event.) We opened up the Aquarium for our members after scheduled hours for an evening of tricks, treats and, most notably, our costumed divers in the GOT.


This is me! My name is Kimmie Banks and I'm currently the GOT co-op from Northeastern University. I've been here for about 4 months now, and I've quickly learned that there is never a dull moment in the GOT. I was really excited to wear a costume in the tank, but isn't easy to think of a costume that is hydrodynamic and won't look like delicious food to our animals. The angelfish were really interested in eating my Bumble Bee outfit, but luckily it stayed intact.

Earlier that day our volunteers and interns had fun carving pumpkins to put in the GOT.




This year we had such a great turn out for volunteer divers, and Lizzie and Brian were no exception.

Amidst all the candy, Popeye encouraged children and adults alike to eat their spinach.



A fearless Spiderman scaled the windows of the GOT with ease. If you could hear her speak underwater, visitors would hear: "My Spidey senses are tingling."



Luckily, we also had the most graceful of creatures in the tank.



Sam as an angelfish and Ariel as a ballerina.



Anna as a jellyfis. I hope Myrtle didn't try to take a bite!



Being at the top of the GOT was so exciting, you never knew what costume would jump in the tank next.

Where's Kristen? Oh, there she is! As Waldo she's tricky to pick out among all the fish.



We thought the tourist season was over, but Andrea just couldn't miss out on such a fun dive.



We've never tried giving the sharks hot dogs, but apparently they wanted a sample.



All staff and volunteers had a blast this year, and based on the smiles and waves we saw through the windows, we're sure families and their friends had a great time too.




Until next year, have a safe and happy Halloween!

#59: What's Happening - Thanks for helping name our new sea turtle!

Today Ari the Kemp's ridley sea turtle made her successful debut in the Giant Ocean Tank (GOT)! Thanks to all of the hundreds of people who submitted names and the thousands of you who voted for their favorite name.


Ari in her new home at the Aquarium

Ari's name has a great conservation message, because it is short for "arribada," which is the massive arrival of female sea turtles to nest. This mostly happens on the beaches of Rancho Nuevo, Mexico, and protecting these nesting areas is extremely important for the protection of the species. Now every time someone asks what Ari's name is, our educators will be able to tell that story!



Ari is such a good name, that a lot of people suggested it. Since we could only have one winner, we selected the person who gave the best description of what an arribada is. That was Sharon B., but some of the other contestants who entered this name include Jenny T., Cathy F., Carole S., Michael N., Ryan B., Helen Z., Dominika, Sam P., Melissa V., Julia, Jack and Alison P., Alex S., Aaron P., Romy M., Jake S., Jenn G., Danielle D., Cindy S., Ashlee D., Norma R., Judi O., Connie B., Junior G. and Steph. Great work, everyone!



We also received some great entries from families who came together to think of great turtle names. Thanks to Molly, Rob, Bo, Callie, Ned and Colin for sending us your entries, and we hope you have fun seeing all the turtles in the GOT during your next visit!



In the meantime, Ari is getting used to her new home, and we'll be keeping you updated on other GOT happenings.

#57 What's Happening - Vote for your favorite sea turtle name!

The Aquarium's new Kemp's ridley sea turtle needs a name, and we're having a contest to name her! Last week we asked turtle fans to submit their favorite sea turtle names, and this week you get to vote on which name is the best! Here's some more information about each of the names you have to choose from.


The submission box gets another name idea last week.

Ari -Vote for this name now!
Ari, short for Arribada, refers to the mass nesting reproductive strategy that is unique to this species. Every year between April and June, thousands of female Kemp's ridley sea turtles arrive at the same beach in Mexico to lay their eggs. Why they synchronize their emergence is largely unknown, but it may serve as a form of predator saturation or swamping.

Cara -Vote for this name now!
Short for carapace, which is the word for the upper shell of sea turtles. The name Cara can also be linked to the late Archie Carr, whose contributions to sea turtle conservation are unsurpassed. You can learn more about the wildlife refuge named for Archie Carr here.

Lora -Vote for this name now!
Aside from a modest number of nests in Texas, The entire population of Kemp's ridley sea turtles next on beaches in Mexico. The people of Mexico refer to these turtles as "parrot turtles" or "Tortuga Lora", for their parrot like beaks. Their beaks allow them to crack open crabs and other shell fish, which are a major component of their diet.

#54 What's Happening - Wetsuit Revenge!

Our co-op students are usually ready to get out of their wetsuits after completing five dives a day for five days straight. Not this week! Our newest co-op, Kimmie, just couldn't bear to part with her wetsuit. Well, actually she got stuck in at after her last dive of the day.

We use our dive gear several times daily and we're really tough on it. It seemed like Kimmie's wetsuit really wanted to put up a fight. After many attempts to free her we decided to bring in the big gun (a.k.a., John with his pliers.)

John cut the top of the zipper off so the suit wasn't badly damaged. Kimmie was able to go home in her regular clothes. I'm happy to say she came back this morning and is ready to dive again!

#52: What's Happening - Counting Fish in New England

When I'm not feeding the more than 600 animals that call the New England Aquarium's Giant Ocean Tank (GOT) their home, I'm fascinated watching animal behaviors that are always going on. While I love diving in the GOT on a regular basis, I got my start diving in the cool New England waters where I watched these same animal behaviors for the last 25 years.



These observations came in handy as the New England Aquarium Dive Club (NEADC) and the Reef Environmental and Educational Foundation (REEF) sponsored the 8th annual Northeast Great Annual Fish Count held up on Cape Ann, Massachusetts. This year, there were 119 divers who submitted 140 surveys and identified 45 different species! All three numbers were records for the eight year old event, which is the largest of it's kind in the country. These divers observed 4 or 5 species that were never observed before, like the Atlantic wolf fish and the Atlantic torpedo ray. So, what did we see and how did we count them? Using underwater slates with waterproof paper, as well as laminated fish ID pictures, we marked down only fish that we could positively identify. They were categorized using "single" for one fish, "few" for 2-10 fish, "many" for 10-100, and "abundant" for over 100.



After the dives, these observations were transferred to survey sheets back at the staging area and submitted. Then came the fun part! This year there were over $8500.00 dollars in prizes including a dive vacation, wetsuits, regulators, fins, masks and a rare opportunity to dive into the GOT here at the New England Aquarium, which is always one of the most sought after prizes!



There was quite a spread of food supplied by the New England Aquarium Dive Club afterward. This year the weather has been very wet but we had a beautiful day for the event. Underwater visibility wasn't the best due to all the rain we've had recently but that's New England diving. This year, there was participation from 7 or 8 different local dive clubs. While the prizes were great incentive, this also gives divers the opportunity to become "citizen scientists" and contribute to helping to address a variety of questions on marine life populations and species to marine scientists. Those of you who are divers, consider joining REEF and fill out a survey form for every dive you do. It's up to all of us to help protect our blue planet.



Be sure to check out the NEADC's Annual Tropical Fish Rescue coming up in September. Tropical fish in New England? Every fall, juvenile tropical fish travel up north in the Gulf stream and end up in the shallow waters in southern New England. As the fall weather begins to cool. so do the ocean temperatures and the tropicals can't handle the cooler temps, so NEADC collects these animals and some have even been introduced into the GOT!

So, don't forget to check out the GOT blog for details on what we found and rescued. It's the thrill of the hunt!

#50: What's Happening - Great Annual Fish Count

As the New England Aquarium celebrates its 40th Anniversary, it gives us a moment to reflect on how we can help to protect our blue planet.

On Saturday, July 25, the New England Aquarium Dive Club (NEADC) and Reef Environmental Education Foundation (REEF) are sponsoring the Great Annual Fish Count (GAFC). This year, our 8th, divers from all over New England will count fish populations at various dive sites on Cape Ann as well as southern Maine. (NEADC recently held a New England fish ID course to familiarize divers with the various species to identify and how to count them.) Data from the event is used to raise awareness among both the diving community and public regarding marine habitats and trends in fish populations and to provide researchers, marine resource managers and policy makers with this useful information.

After the dives, everyone meets back at the staging area to fill out surveys reporting what they counted. They are given raffle tickets for chances to win more than $8,500 in prizes! Some of the prizes include a dive vacation to Bonaire, underwater cameras, wetsuits, regulators, fins, and of course, the rare privilege to dive into the Giant Ocean Tank here at the New England Aquarium! The NEADC is providing lots of food back at Stage Fort Park afterward as well.

If you're a diver and want to come out and count fish with us, check out the event's website at or visit the Dive Club website and REEF website for more information. And, don't forget to check back in with this blog in a few weeks for information and pictures of what we saw and counted and how we did it!

#40 What's Happening - Please Vote for the Aquarium

We're asking for everyone to help us by voting for the Aquarium in this year's Partners in Preservation grant contest. You can vote EVERY SINGLE DAY until May 17th. Cast your vote on the Partners in Preservation website. You can also sign up to get reminders form the Aquarium to vote.



What is the contest?
American Express, in partnership with the National Trust for Historic Preservation, has identified historic places throughout the Boston area that reflect the region's rich and diverse cultural heritage, and we're in the top 25! If the Aquarium gets the most votes we will get a $100,000 grant to restore the interior concrete to its original finish.

Why are we being recognized as a historic structure?
The Aquarium is considered to be the first modern aquarium. Its architecture and habitat-based exhibits influenced future aquariums. The centerpiece 200,000-gallon Giant Ocean Tank was the first of its kind, and is considered a milestone in aquarium layout and design. Among other firsts was the tide pool touch tank, now an aquarium standard. The Aquarium was the first commission for Cambridge Seven Associates, which has since designed 11 aquariums worldwide. This significant and daring project helped stimulate redevelopment of Boston's run-down wharf district and was a catalyst for the revival of Boston's historic waterfront.

Here's a picture of the Giant Ocean Tank when it was first built:



You can vote once every day, so please get out there and show your support! The sharks, rays, sea turtles and fishes will all appreciate it :)

THANK YOU!

#34: What's Happening - 55th Boston Sea Rovers Clinic

Hi,
My name is Paul and I am a senior penguin keeper here at the aquarium. I am also a back up diver for the Giant Ocean Tank dive team. Working with this group over the years has given me the opportunity to participate in many animal exams, transports, and several diving collection expeditions. It has also connected me to the many different elements of the diving industry and community.

About 5 years ago I was introduced to the oldest dive club in the country, The Boston Sea Rovers. Since 1954, this group (made up of mainly volunteers) has gotten together with the mission of holding a clinic with the hopes of "Raising the Level of Knowledge of the Underwater World." Some of the world's greatest oceanographers and explorers like Jacque Cousteau, Dr. Robert Ballard, and Dr. Sylvia Earle, have participated in these events. This collection of avid divers is known internationally for having the "Longest Running Underwater Show on Earth."

A quote from their website states "The history of the Sea Rovers is, in many ways, the history of scuba diving." The funds generated from the clinics help support various internships and non-profits like SeaMark Vision Clinic (pdf) and the Cotting School for children with special needs. This March 7th & 8th will mark the 55th time that the clinic will be held. They will have workshops, seminars, and a world renowned film festival. Below are some pictures of the clinic. I will be volunteering with them that weekend and invite you to join us.

Cheers!

#32: What's Happening - See Turtle Contest Winner Feeds Myrtle!

Myrtle the green sea turtle is fed small meals at least five times a day. This as opposed to fewer big meals helps to promote the natural green sea turtle feeding behavior called "grazing." Myrtle is usually fed by New England Aquarium staff and volunteers, but today two very lucky visitors got an opportunity to give it a shot!



DJ won the Aquarium's "See Turtle" photo contest, and his prize was to feed the Aquarium's biggest turtle. The feeding was covered on Channel 7 News, and here's a slideshow of what happened:

#27: What's Happening - 2008 Things To Remember...

Now that we've moved into an exciting new year, it's easy to plow forward without looking back. But before getting too far into '09, I wanted to put time on hold for just a moment and reminisce over some of the interesting things that the Giant Ocean Tank dive staff experienced during ...



The Best of 2008


  • Sarah went to Utila in Honduras to obtain her PADI Dive Instructor's certification, and actually managed to squeeze in some time working with the Whale Shark & Oceanic Research Center. Here's a photo of a whale shark from her trip:



  • We had two successful Bahamas collecting expeditions (May and September) - where we collected under permit several hundred animals for exhibit. What's so great about these expeditions is that anyone can participate. If you want to go on the next one this Spring email Sarah at staylor@neaq.org.



  • We got a brand spanking new refrigerator in the food prep room! (This ain't no run-of-the-mill 'fridge either.)




  • We hand-delivered over 14,600 lbs. of protein (such as chopped or whole fish, shrimp, squid, clams, crabs, etc.) and produce (such as lettuce, brussels sprouts, cabbage, broccoli, etc.) to the always hungry mouths of the tank's inhabitants.






  • We had two equally great high school interns - Oriana and Naomi.


  • We also added three new, and invaluable, folks to the ranks of the GOT volunteers - Caitlin, Armando and Jenna.


  • Topping off the people list we had two fantastic Northeastern co-ops - John and Stephany. Each one conducted over three hundred dives in the GOT.


  • We conducted 4,026 GOT dives, spending a whopping 2,632 hours underwater! (That equates to one person spending over three and a half months underwater, 24 hours a day...)













And the exciting thing is--who knows what's going to happen in 2009!

#25: What's Happening - Testing The Anodes

Maintaining the Giant Ocean Tank, which has been on exhibit since 1969 can often at times be challenging. With a total of 67 windows, only a few have had to be replaced. The window frames are protected from corrosion with the use of an anode. An anode is a sacrificial corrosion device. Once installed they require a weekly cleaning, and quarterly testing.
Link


Testing the anodes requires a team of at least two people. The windows are numbered 1 to 67. A diver places the probe tip on the window frame.

On the surface the information is gathered and recorded for each window.

#21: What's Happening - Thanksgiving Day at the Aquarium

It's Thanksgiving Day, and what does that mean? The Aquarium is closed for the day. But wait, what about the animals? They don't know it's Thanksgiving, and they expect to eat like any other day, so it's another day at the office for a few select aquarists ... like me!



An atypical scene out on the front plaza - no people.



High-calorie foods like donuts are a must for a diver, especially on Thanksgiving when it's important to carbo-load in preparation for the evening's turkey feast.



Brian is a dedicated Monday volunteer who came in to help us out on this holiday. Here, he is showing off his shark food prep skills. Today's menu consists of squid (Note: the coffee is NOT for the sharks).



The dive team: Me, John, and Brian.



We decided to go for a pre-feed swim this morning, to scrub out the algae from the surface skimmer gutters. If left untended, it grows into thick mats...



... and as you can see from this video, Myrtle the green sea turtle thinks it's really tasty!



And of course, Thanksgiving wouldn't be Thanksgiving without tossing the football around.


As we all know, Thanksgiving is for overeating. However, our sharks ended up not being very hungry, as shown here by Markham's (our male sand tiger shark) complete disinterest in this squid I offered him.



Happy Thanksgiving!

#16: What's Happening - Halloween Costume Diving

It's my favorite time of year - Halloween! Each year, the Aquarium throws a party exclusively for members and their guests, called Fish, Fun & Fright. To add to the festivities, we carve a few dozen pumpkins and put the Jack-O-Lanterns into the Giant Ocean Tank around the reef with glow sticks inside. Myrtle and some of the angelfishes like it when we do this, as some of them find pumpkins tasty!



decoration/turtle foodUm... is that a shark?

Many of the guests come in costume, so since we don't like for everyone else to have all the fun, we dive in costume in the GOT as well! It can be a bit tricky coming up with a costume that will work underwater. You have to consider the material, reduced gravity, being able to equalize your ears, entanglement, etc. We had seven unique and fun costumes this year.

Here is Mike as a clown, always a crowd favorite.


Don wore a Davy Jones (from Pirates of the Caribbean) mask, which he said prevented him from seeing much of anything during his dive.


Paul, for his costume, borrowed a vest and a hardhat from Turner Construction Company, who is heading up the construction of the New Balance Foundation Marine Mammal Center (coming Summer 2009).


Andrea's idea was to incorporate the SCUBA backpack into her costume, and was a Ghostbuster.


Liz (right) was a fairy and had a lot fun casting spells on the visitors through the windows. She won 'best underwater costume', as voted by all costumed divers. I (left) dressed up as a man on the moon, and walked around weightless-like on the bottom of the tank.


Sam, arrrgh, dove in as a pirate (with a fake sword I promise), and took 2nd prize.


Happy Halloween!

#15: What's Happening - Lost Wedding Ring is Found!

In early July, a guest diver lost his wedding ring while SCUBA diving in the Giant Ocean Tank. Bob, a creative director with Boston area advertising agency Mullen, was given the chance to dive in the GOT after helping create the award winning marketing campaign for the "Sharks & Rays" exhibit. After the dive he realized that his wedding ring was missing! His best guess was that he lost it while scrubbing the shell of Myrtle, our 560 pound green sea turtle.

Bob Pirrmann (left), lost his ring in the GOT. Mike (right) found it.

Three months later, I was vacuuming up food debris in the sandy area between some finger coral during the 1:15 cleaning dive. When the debris was gone, I noticed a round shape that I thought was a coin. After vacuuming some more, I realized what it was. It was the ring!



Mike passes the Bob his wedding ring in the Giant Ocean Tank.

As divers, we often find things that drop into the GOT. We have a collection of sunglasses, cameras, cell phones, and baby pacifiers. But was a unique find and it felt great to return the ring back to Bob. He even came back for another dive so I could show him where his ring has rested for the last few months.

#12: What's Happening - Shark Transports


Our last blog entry focused on how we ship small fish from our Bahamas collecting expedition, but what about the big guys? Transporting sharks is a whole different story. It requires a lot of specialized equipment and a huge team of experienced staff and volunteers. Senior staff develop a plan weeks before the actual transport. One of the most important preparations is equipping the transport truck with the necessary life support system.




For a large sandtiger shark, we use a 9-foot fiberglass tank with a rapid sand filter and hayward pump to keep the water clean and flowing. It is also essential to continuously bubble oxygen into the water. While on the road, dissolved oxygen and temperature are monitored constantly to ensure the best water quality for the duration of the trip.


Once the transport team arrives at the Aquarium, they are met by another team who will assist in getting the shark from the transport truck to the Giant Ocean Tank exhibit (GOT). First, a large stretcher designed specifically for shark handling is lowered into the transport tank.




Once the shark is gently coaxed into the stretcher, several staff and volunteers lift the shark up and out of the truck.


With the shark now out of water, time is of the essence. Staff must get the shark from the loading dock on the first floor to the GOT on the 4th floor as swiftly as possible.



Once at the top of the exhibit, the stretcher is attached to an electronic hoist and slowly lowered into the GOT.



Two staff divers accept the stretcher, and bring the shark to the bottom of the tank. Once the stretcher is opened, it generally it takes anywhere from 5 to 30 minutes for the shark to come out and begin swimming. Check out this video of divers introducing the shark to the Giant Ocean Tank:



We currently have three sand tiger sharks; all were acclimated to the GOT using this transport method.

#9: What's Happening - Testing Science


Not every marine scientist has a twenty-three foot deep pool filled with 200,000 gallons of salt water sitting right next his or her office. Add a smattering of creatures (some 650+) and it's a researcher's dream come true.

Dr. Joshua Idjadi, a marine scientist for the New England Aquarium's Research Department, just so happens to have such a pool sitting next to his office, and he's not one to let such resources go to waste.




Not two weeks has passed since Dr. Idjadi had completed his checkout dive in the Giant Ocean Tank and he's already plunging back into the exhibit to test the effectiveness of something known as an "acoustical pop-up."

Talking about the long-term New England Aquarium study involving the Liquified Natural Gas (LNG) deepwater port off Gloucester Harbor, Dr. Idjadi says, "One of our research goals is to track fish movements around the LNG port. This means we have to deploy an array of expensive fish tracking devices in 300 feet of water. To retrieve these devices, we are using acoustic releases (the long gray tube shown in the images) which allow us to remotely release our tracking devices from the bottom. They work by receiving a sound signal generated by a transmitter located on the surface (on a boat, for instance), triggering the corrosion of two metal loops which hold the device to the bottom, and sending it floating to the surface. We wanted to be sure the releases were working properly so we tested them in the GOT before using them in the field. The test was successful! "



Here's some images from Tuesday's test (click to enlarge).



I was lucky enough to watch the experiment from a pretty good vantage point and therefore had a chance to see an acoustical pop-up in action.



Not only was the experiment a complete success, but it provided an opportunity to educate visitors on one of the many research activities the Aquarium conducts all over our blue planet. Here, researcher John Mandleman explains what is going on to people gathered at the top of the Giant Ocean Tank.



Oh, and it helped keep some of our angelfish entertained as well...

#7: What's Happening - First Contact



Standing on the dive platform above the clear, warm water of the Giant Ocean Tank (GOT), creatures of all shapes and sizes circling below me, one question I'm often asked by the visitors surrounding the top of the exhibit is, "How do you get to dive in that tank?" Indeed, it's a question I myself once asked when I was visiting the aquarium as a kid, some twenty-odd years ago.





Though there are a variety of ways certified SCUBA divers can experience the GOT as a guest diver, such as through the New England Aquarium Dive Club, raffles or auctions offered through charitable organizations, or even participating in annual NEAq collecting expeditions into the Bahamas, the majority of divers seen swimming alongside the six hundred plus inhabitants of the GOT are NEAq Scientific Divers. These divers, both Aquarium staff and volunteers, perform a wide variety of tasks critical to the success of such a large and complicated exhibit. They also undertake a wide variety of diving activities for the Aquarium in both local waters and at points scattered all across the globe.






The first step in becoming a Scientific Diver for the New England Aquarium is a wet one--it's the dreaded, and so very exciting, checkout dive. A prerequisite for Scientific Diver candidates is to be SCUBA certified, and one of my jobs as the Aquarium's Diving Safety Officer is to ensure that these candidates are adequately comfortable and competent underwater.




What better way to test this then to bring them into the GOT and have them perform all the basic SCUBA skills they learned in their Open Water certification class--but with a twist.



This time they have to do these skills while 300lb sand tiger sharks circle overhead, loggerhead turtles creep up behind them, and literally hundreds of spectators watch their every move only inches away.





Not many divers get the unique experience of buddy breathing while a young child drinks in every detail, wide-eyed in wonder.



Wide-eyed, that's the expression I see in basically every candidate splashing into the tank for the first time, as they experience a sense of sensory overload. And I'm proud of every one of them as I watch that expression morph into one of elation as I shake their hand at the completion of the skills review.

They have to get past me, and the GOT, before they can start their education as a Scientific Diver for the Aquarium, but with that first contact I know that NEAq has gained another valuable diver.

#4: What's Happening - Annual Sea Turtle Exams

There are seven species of sea turtles in the world; all are recognized as endangered or threatened. Six of the seven species are found in U.S. waters. Every fall hundreds of tropical and sub-tropical sea turtles end up in Northern waters along the Eastern seaboard. It is not entirely clear why this occurs, but there are two possible theories. Some scientists believe that New England provides an important foraging ground for young sea turtles, and their migration here is deliberate. Others believe small juvenile sea turtles get caught up in the Gulf Stream and their arrival here is involuntary. Either way, when water temperatures drop, many of these turtles suffer from hypothermia, and in some cases severe frost bite. The New England Aquarium's Rescue and Rehabilitation Center is a member of a stranding network that rescues these cold-stunned turtles. Our goal is to nurse them back to health and eventually release them back into the wild.

The Giant Ocean Tank offers a unique opportunity for endangered and threatened sea turtles that have been classified as non-releasable. This 200,000 gallon, 23 foot deep Caribbean reef exhibit provides sea turtles with an ideal habitat in which to live out their lives. Over the past 30 years, loggerheads, Kemp's ridleys, hawksbills, and green sea turtles have thrived in the Giant Ocean Tank. We currently have four sea turtles; two loggerheads (Carolina and Retread), one Kemp's ridley (Scute), and one green sea turtle (Myrtle).

Like all of our animals, they benefit from excellent water quality, sound nutrition and first-rate veterinary care. To ensure the good health of our turtles, we conduct medical exams every summer. This year's exams took place on Wednesday, August 6 and Thursday, August 7. Completing the annual sea turtle exams is an enormous effort, requiring the participation of many individuals from a variety of departments.



Staff biologists (the divers) from the Fishes Department collect the turtles from the exhibit and make sure everything is in place for the exams. Veterinary staff and biologists from our Animal Health Division perform all the diagnostic work, and our Educators interpret the entire procedure for our visitors. The procedure starts with the "turtle catch." Two divers enter the exhibit and gently grasp the turtle under the fore flippers. The turtle is swiftly escorted to the surface of the exhibit and placed into a large box designed specifically for sea turtle removal.



The box is then lifted out of the exhibit and into an adjoining support area with an electronic hoist. The turtle is lifted out of the box and onto a small exam table. Both loggerheads weigh well over 100 pounds, so it can take up to four individuals to accomplish this. Once the turtle is settled on the table, the veterinarians and biologists begin their work.



They begin by weighing and measuring the turtle. They carefully examine the eyes, mouth, flippers and shell, looking for any abnormalities. A blood sample is taken from a vessel on the top of the turtle's neck. The exam is concluded with an ultrasound which enables the vets to get a heart rate and determine if there is any egg development. The turtle is then placed back in the exam box, and returned to the exhibit. Staff divers monitor the animal's behavior for several hours after the exam.

Myrtle, our green turtle weighs around 550 pounds, and is too big for the exam table. Her exam is conducted in the box at the surface of the exhibit. Our loggerheads weighed in at 196 (Retread) and 152 (Carolina). Scute, our little ridley, weighs only 52 pounds. All four turtles are in good overall health, and will likely grace the Giant Ocean Tank for many years to come.
