#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!

#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.

#89: Toothbrushing 102: The Rotary Toothbrush

The harbor seals have been comfortable getting their teeth brushed with a manual toothbrush for some time, so now we're introducing a rotary toothbrush. This battery-operated toothbrush has a smaller head that quickly rotates in circles. We share a couple of brush bases, but as you see in the picture, everyone has their own brush head. The letters on the heads tell us whose toothbrush it is. For example, "CA" stands for Cayenne.




Having a toothbrush that moves on it's own takes some getting used to. We took it slow, but as you can see from the picture above, 6 of the 7 seals are using the rotary toothbrush for some or all of their toothbrushing. Here is a video of Cayenne getting her teeth brushed with the rotary toothbrush - if you listen carefully you can even hear the sound of the toothbrush.

#83: Tooth Brushing 101

In a previous post, I showed you a visit from our veterinary dentist Dr. Laura LeVan. What do you think we do with the seals between visits from the dentist? We brush their teeth!


Everyday we brush the seal's teeth to prevent plaque, gingivitis and fish breath. We use regular toothbrushes from the grocery store and special malt-flavored toothpaste made for dogs and cats. (We did a number of taste tests and the malt flavored was the preferred choice for the seals - even over the seafood flavored!) We also have a mouth rinse that is applied directly to their teeth and gums. We haven't been able to teach them to gargle.

Our Sunday volunteers Katie and Janine show the seals' mouthwash, toothpaste, and toothbrushes.

Training one of the animals to sit comfortably while we brush their teeth may sound a little hard to believe, I can assure you all of the seals are great with it. Check it out!
