#136: Chuck the flying harbor seal

Porpoising is one of the many impressive behaviors that harbor seals do naturally. By leaping out of the water, they are able to take a quick breath of air and a look around when either playing or trying to get out of harm's way.



Many of our seals have been trained to do this behavior on signal - it's a great way for us to show off a cool natural behavior while keeping the seals active. Check out this video of Chuck:

#129: Harbor Seal Puzzle

Amelia has always shown a lot of interest in a particular orange boomer ball toy that we stuff with fish. Now we have decided to take it one step further by making a puzzle for her. So she can learn how it works we started with an easy one.



We modified two clear, small animal exercise balls by drilling holes in them, then placed some capelin pieces in the big ball and gave it to the seals. Since it looked a little different from the original toy, it took Amelia a little bit to figure out what it was, but once she did she was really into it. And she wasn't the only one; Trumpet, Chuck, Cayenne, and Smoke all took turns. Now the next step is to start placing the fish inside the little ball and put that inside the big ball- then they will really have to move the toy to get the fish out.

#122: Happy Birthday to Trumpet, Cayenne, and Chuck!


Trumpet and her two kids, Cayenne and Chuck, have birthdays within one day of each other so we decided to have a group celebration this weekend. Cayenne turns 16 tomorrow, Trumpet turns 24 on Sunday, and Chuck is 14 years old Monday! We celebrated with a birthday cake, but instead of having one made out of ice cream, their cake was made out of capelin and squid. Yum! Of course, we had to take some birthday pictures.






Happy Birthday!

#121: Jellies in the Harbor Seal Exhibit

We are always trying to come up with new enrichment ideas for the seals, and in fact, this was one of my goals for the year. Yesterday we introduced 10 moonjellies to the harbor seal exhibit, with the hopes that the seals would enjoy something that actively moved throughout the water column.



Most of the seals were resting, so they didn't pay any attention to the jellies at all, but they did attract Chuck's attention.

Check it out!

#120: Seal of the Week--Chacoda

While our fur seals are on vacation, I thought that this would be a great opportunity to give you an in depth introduction to each of our Atlantic harbor seals. Each week we will highlight one of our harbor seals and give you some cool facts and amazing behaviors that make each of our animals unique.

This week the star of the show is Chacoda!


Chacoda was born on June 8, 1995. He is going to be fourteen years old next week! His mom is Trumpet and he has an older sister named Cayenne. Chacoda's name was chosen by his trainers and is a combination of two different words ... Chauncy (a lobster pier in Maine that a lot of trainers enjoyed) and Coda (the end of a musical piece, since Chacoda's Mom is named Trumpet). Despite all of the thought that went into his name, more often than not we just call him Chuck!

Chuck is part of our spotted family of seals. You can see this by taking a look at the picture above. He has dark spots all along his belly. Below, you can see that he also has very large nostrils; these help to distinguish him from his sister Cayenne who has more petite features. Currently Chuck weighs about 155 lbs. but has been known to reach weights in the 180's depending on the time of year.


Although Chuck is our youngest seal, he has learned a vast array of behaviors. One of the most well known behaviors is his ability to vocalize. Chuck can often be heard making deep guttural sounds that echo throughout the exhibit and even down the front plaza of the Aquarium! Like his grandfather Hoover, and his father Rigel, Chuck has learned to say a few different words and phrases. Stay tuned for a future post from Cheryl for more info!

Wearing an underwater camera is another cool behavior that Chuck has under his belt. Paul trained this behavior last year. Now you can get a view of our exhibit from the harbor seals' perspective. Paul is also in the process of training Chuck to do a back flip. This is an awesome behavior to watch because it shows how athletic the seals are. If Chuck gets enough speed and height, he can propel himself completely out of the water, flip backwards in a full 360 degree circle and then land back in the water in his original position.

Erin is also Chuck's trainer and she has done some amazing things with him. All of our seals allow us to brush their teeth using manual toothbrushes. But sometimes it takes a little more to handle seal plaque. So, over the past six months, Erin has not only trained Chuck to allow a rotary toothbrush on his teeth, they have now moved up to a Sonicare toothbrush! For those of you who have one, you know the sound that they make and how much they vibrate. It takes a lot of work to train a seal to accept a toothbrush like that, but now Chuck lets Erin brush his teeth with the Sonicare every day. Only the best for this guy!

These are just a few examples of the amazing behaviors that Chacoda has learned here at the Aquarium. Chacoda can be found living with the rest of our Atlantic harbor seal colony in their exhibit on the front plaza. Come by sometime to see a session. There are four each day and you never know what behaviors Chuck will be showing off!

#113: A Seal's Banana



For the last few months, I have been working on training Chuck to do a behavior we call a Banana. Interesting name, yes, but pretty fitting since it describes a natural resting behavior where seals lay on their side and lift their head and hind end up slightly, creating a shape that resembles a banana. With this behavior though, I wanted Chuck's final body position to be a little bit more exaggerated. What do you think?

#102: Who's Who?

One of the most popular questions the trainers hear is "How do you tell the harbor seals apart?" The answer sounds simple; just by looking at them, but it can take a long time if you don't see the seals every day.

First you need to know who is in the exhibit. We currently have seven Atlantic harbor seals in the plaza exhibit--two males and five females. We can divide them into two easily identifiable groups, the 'spotted' and the 'non-spotted' seals. The spotted seals have distinct dark spots on their necks and bellies. All of the 'spotted' seals are related.

Our spotted seals are Trumpet Cayenne & Chacoda:

Link

The non-spotted family: Amelia, Reggae, and Smoke:

Look at the picture below of the non-spotted family. Can you tell who is who? How did you tell?



Last but not least, our seventh seal is Lana. She is not related to any of the other seals, but she most resembles the non-spotted family.



Other than the obvious spot patterns, we look for differences in the shape of the head, nose, and eyes. They also differ in their body length and girth, but this can be deceiving. The seals' weight can fluctuate between 10 and 30 pounds depending on the time of year, so weight isn't a reliable way to distinguish individuals.

Now that you've looked at the pictures, will you be able to tell the seals apart on your next trip to the Aquarium? Don't worry if you can't. Start by telling the spotted from the non-spotted first. It took all of us a while to figure out Who's Who too and we see them every day!

#99: "Fishsicle"-- Chacoda's Ice Toy



Enrichment is a big part of what we do every day to make sure the animals are stimulated in their environment. Ice toys or"fishicles" are one of their favorites. Here's a "seal's eye view" of Chuck (Chacoda) playing with an ice toy during a "Play With the Seals" program. Our program participant is standing on the rocks above and is using the other end of the blue car wash strip to drag the toy through the water to entice Chuck though he doesn't look like he needs much enticing!



It looks like he has it all to himself too until Mom (Trumpet) comes over to check it out.

#93: Chacoda featured in the Boston Globe




All of our recent posts on toothbrushing seems to have attracted some attention, because on Wednesday, Feb. 4, Chacoda and I did an interview with the Boston Globe to celebrate National Children's Dental Health Month (it is also National Pet Dental Health Month).




While Chuck did seem a little distracted by the camera at times, he was great while I brushed his teeth and the photographer was able to get some really great shots. Not only did the story make the front page of Boston.com that afternoon, but it was also featured on the front page of the Boston Globe's Metro section on Thursday!

#91: Toothbrushing 103: The Sonicare Brush


While Chacoda was regularly having his teeth brushed with the rotary toothbrush (and really great at it too), we noticed that there was some plaque build-up on his back teeth that, while not bad, just wasn't budging. So this past month I introduced Chuck to the Sonicare toothbrush with the hopes that it would just blast that plaque right off.





As you can see from this picture, the Sonicare brush is overall much larger, has a head that is similar in size to the manual toothbrushes, but what you can't see is that it vibrates significantly more than the rotary toothbrush (it will vibrate the toothpaste right off).

Since I have never used a Sonicare brush myself, I tried it first (when it was brand new and clean) so that I would have a better idea of what Chuck would be experiencing. Let me tell you, that brush makes your mouth tickle! I also learned from those that have regularly used this type of brush that it can cause some gum sensitivity in the beginning.

Taking these two things into consideration, I chose to start with Chuck's bottom teeth and only when he was very comfortable, move on to the top. My thought was that this would allow Chuck to become accustomed to the sensation of the brush, while minimizing any mouth sensitivity he may experience.


So far it's working well. As of today, Chuck will allow me to continue to brush his top teeth with the rotary brush while brushing his bottom teeth with the new Sonicare brush! This video shows just how comfortable Chuck is with the new Sonicare (and if you look closely in the beginning, you will notice the toothpaste nearly flying off the brush)!



Of course, how are we going to know for sure that this brush (or any) are working? Here is a picture of Chuck's mouth before we started using the Sonicare toothbrush. You may notice that the teeth in the back are darker than the ones in the front - that is because of that plaque build-up I mentioned earlier. In a few weeks I will take another picture of Chuck's teeth to check how the new toothbrush is working. So be sure to check back and hopefully we can see a difference.

#81: Just Another Day at the Office

Rochelle and I were the only two trainers on last week. With seven seals to feed you might think it would be difficult, but this is where those name targets come in handy. Each of us did two sessions with five seals at a time, which allowed the other trainer to focus on two. It was enriching for both us and the seals; you will notice that Rochelle and I didn't always feed the same animals or even line them up in the same order, but by using those name targets we were able to keep the five seals together calmly and give everyone the attention they deserved.


Here is Rochelle with (starting from the top) Trumpet, Lana, Smoke, Reggae, and Amelia.
Can you find all five targets?


In this picture I am working with (from the top) Cayenne, Chuck, Smoke, Reggae, and Lana. With the other four seals focusing on their name targets I am able to give Smoke some of her daily eye drops.

I wonder what today will bring?

#78: A Trainer's Holiday Story

Once upon a time there was a group of talented trainers who worked at the New England Aquarium. These trainers decided to send holiday cards to all their friends to let them know they were thinking of them. "What sort of card should we send?" they wondered. They thought and they thought and they thought. Then one said, "Let's have our photogenic harbor seals kiss under mistletoe!" "Brilliant!" shouted the trainers with glee.

So one of the trainers gathered some fake mistletoe (because real mistletoe is dangerous) and held it above Cayenne and Chuck. For three days the trainers tried to get the perfect picture, but this wasn't as easy as they had thought. The mistletoe had to hang lower to be seen in the picture, Cayenne didn't like the mistletoe so close to her head and Chuck kept smelling the fake mistletoe and leaving in disgust--yuck! At the end of the third day when all the trainers were starting to get discouraged they reviewed their pictures and what did they find...

... THE MOST PERFECT PICTURE THEY HAD EVER SEEN!

They quickly uploaded it, because these trainers are computer-savvy, and created a card to send to all of their friends. So to you, our friend, the Marine Mammal Department wishes you a happy holiday season!




The End.

#70: More Playtime!



As you all know by now, there are many different ways to enrich our seals. Here is a short clip of Rochelle and I playing with Chacoda and his sister Cayenne through the glass.



They really get a kick out of people playing with them at the shallow end of the exhibit. Here's another post that has a video of that. Try it sometime--just remember not to bang on the glass. Sometimes you can even catch Cayenne waiting to play!

#68: Sealcam

One of the major hurdles in doing research on most marine animals is the fact that much of what they do and experience takes place under water. Even diving underwater to observe them is problematic because of our own physical limitations as well as the inherent dangers divers sometimes encounter.

In 1986, during a dive trip off Belize, a shark approached marine biologist and filmmaker, Greg Marshall. As the shark swam off, Marshall noticed a remora (sucker fish) attached to it. It occurred to Marshall that if he could replace the remora with an underwater video camera, he would be able to see first hand how a shark moves through and functions in its environment. Thus, the "Crittercam" was born.

In 1987 Marshall strapped the first awkward crittercam prototype to the back of a captive loggerhead turtle. Since then, crittercams have evolved from large and awkward systems into smaller, more hydrodynamic pieces of equipment. This new technology has provided scientists with an unprecedented look into the lives of all sorts of underwater creatures. Other versions of the crittercam have even been designed for and successfully deployed on terrestrial mammals such as bears and lions.

Here at the New England Aquarium, two of our harbor seals, Amelia and Chacoda, have been trained to wear a harness to which a video camera and underwater housing have been attached. This video gives you an idea of how I went about teaching the seals to be comfortable with the various components of the harness and video housing.



Though the present version of our "crittercam" might be as unwieldy and awkward as Greg Marshall's first prototype, the chance to see what Chacoda and Amelia see as they move through their exhibit is exciting and fun.

As we gradually work out the kinks and design problems in our crittercam system we'll give you the opportunity to get a "seal's eye view" of our exhibit and it's residents. If you're interested in learning more about "Crittercams" go to the National Geographic crittercam website and find out more about this exciting research tool and the look that it's given us into the "hidden" lives of all types of animals.

#66: What does that mean?



Alright, we get it. Sometimes we use terms that make sense to us, but not necessarily to you. So here are a few of the terms that you might find useful when we talk about training:


Signal: Any touch, word, sound or visible gesture that cues the animals to do a particular behavior. For example: saying the word "Wave" directs a seal to move their flipper back and forth. The word wave is a verbal signal.

Putting our hands out and moving from side to side is a gesture that directs the seals to dance. We call this signal a hand signal.

Touching the top of a seal's nose is a signal that cues them to exhale. The touch is called a tactile signal.

Here you can see Jenny giving Lana the hand signal to dance - notice that Lana is raising her left flipper out of the water to mirror Jenny's right hand. Check out this video of dancing behavior.


Bridge: A signal that is used to indicate the precise instant that the seal did something correctly. When the seal hears or feels the bridge, they immediately stop what they're doing and look to the trainer for fish or other reinforcement. It "bridges" the time between the behavior and reinforcement. Like a signal, a bridge can be visual, auditory or tactile.

Some of the bridges that we use include saying the word "Good," a short blow on a whistle, or two gentle taps on the seal's body.

Here is Baranov using his bridge...

...and Paul is using his whistle bridge.





Reinforcement: Anything the animal wants, needs or wants more of. Here at the Aquarium, our main reinforcement for the seals is fish, but it can also be a favorite toy, a scratch on the chin or any number of things. It's good to have multiple types of reinforcement--just like people, each seal has it's own likes and dislikes which can change over time. Also, not all seals like the same thing. One seal might enjoy a scratch under the chin while another one may not want to be touched.


Here, Jenny is using fish to reinforce Lana...



...but sometimes Lana likes to have her neck scratched.




Target: Any object the animal is taught to touch with their nose, flipper or other part of their body. Targets

provide a focal point and can be used to train any behavior. The seals can be comfortable targeting for several minutes during ultra sound or blood sampling. Gradually raising the height of a target over the water helps teach a seal where to jump. Here at the Aquarium, we use three types of targets: a hand target, a target pole with a bead or ball target on the end, and a name target.

Each seal has a specific object for their name target. At the start of each training session, the seals will look or listen for their particular target. When they find it, they know where in the exhibit their session will take place and which trainer will do their training session.

Here you see Smoke is targeting on a trainers hand while Reggae targets on his name target (a plastic tire) and Amelia targets on her name target (a black plastic disc with slits in it). If you look in the background you will also see examples of other name targets--notice how they are all different.

In this video you can see how they all work together:


When I want to ask Chuck and Cayenne to go to their Name targets, I point to the targets (hand signal) while saying the word "Target" (verbal signal). Once Chuck and Cayenne touch their nose to their individual targets, I will say the word "Good" (bridge) and feed them some fish (reinforcement).

Using these four tools correctly is what has allowed us to train so many behaviors. It's fun. Try it with your friends!

#53: Synchronized Porpoising


I recently decided that I would like to train a synchronized porpoise with Chuck and Cayenne. When you choose a behavior to train, you must first decide what you would like the finished behavior to look like. Otherwise, how will you - know when you are done? In this case, I wanted to give the signal and have Chuck and Cayenne porpoise (jump up out of the water) at the exact same time until I gave them the signal to stop (bridge). Once I figured that out, I was able to plan out the steps I would take to get there. Since porpoising is a behavior both Chuck and Cayenne already know, I chose to start here. I give Chuck and Cayenne their porpoise signal (rotate my extended right arm in a circle backwards up over my shoulder) and blow my whistle (bridge) only when they jump up out of the water at the same time. The idea is that they will start to realize they are only being bridged when they porpoise together and will start to offer it more.

In this video, you will see that they both respond to the signal immediately, but that in the beginning, they are jumping out of the water at different times. Once they jump out of the water together, listen for the whistle sound, that is the bridge. The whistle bridge is very long and loud because it didn't seem like they were listening to it. I wanted to make sure that they heard it. Once they have stopped and returned to me, I reinforce the behavior with a lot of fish.





Stay tuned to see our progress.

#51: Free Swimming with the Harbor Seals

We have recently started free swims with the Atlantic harbor seals. What exactly is a free swim you ask? For us, it is any time a person is in the water with the seals outside of a training session or cleaning dive. We consider free swims to be a type of enrichment for the seals (and of course the trainers). Since it is very new and we want the seals to be comfortable with us hanging out in the exhibit, we will start by going in for short periods of time, taking a break, then going back in.



In this video, you can see Rochelle doing one of the first free swims with the seals. In her first short swim, Amelia comes right over to check her out. In the second swim, Rochelle has picked up a toy to see if anyone is interested and Chuck swims by while Cayenne checks her out from a distance (look at the top left corner). In the third swim, Trumpet checks her out from a distance. I wonder if they will come any closer?...Check back to see!

#21: True Seals

This is one of the commonly asked questions here at the New England Aquarium and I am here to answer it for all of you who, I know, are just dying to know. And the answer is ... DRUMROLL PLEASE .................. NOTHING!

But my blog cannot and will not end with such a vague answer!

Sea lions are a type of seal that have external ear flaps, can rotate their hind flippers under their bodies and "walk" on land. They use long front flippers for swimming and standing, and have LOTS of blubber (or fat). Fur seals look a lot like sea lions and have almost the same physical characteristics, except they don't have all that blubber to help keep them warm. They have, you guessed it, fur! Both sea lions and fur seals are in the same family and referred to as "eared seals."

You can see the ear flaps and upright posture of Guthrie, a male sea lion:















and Cordova, a female Northern fur seal:
















True seals, sometimes referred to as "earless seals," are in another family. This includes all other seals except sea lions, fur seals, and walrus. True seals don't have external ear flaps, they use their hind flippers for swimming, they have a lot of blubber, and short front flippers so they slug around on land. Chaconda, one of our male Atlantic Harbor Seals, is an example of a true seal:

















When put side by side, you can really see the similarities and differences. Here at the New England Aquarium, we currently have Atlantic harbor seals and Northern fur seals.

#8: Man Diving



This picture, titled "Man Diving," was created by a 12-year old. Impressed? Now, what if we told you it was created by our 12 year-old male Atlantic harbor seal, Chacoda? Bet you are impressed now. Painting is a behavior that 5 of our 7 harbor seals know and each animal has developed their own unique style. Since seals are colorblind, the trainers will pick out the colors, but the animals create the masterpiece.
