#35: Seal Eyes

Look Into My Eyes

In this picture you can see a great shot of Chainsaw's eyes. Most would think that the mottled look to the eye ball is a bit odd. For Chainsaw, this is a genetic disorder which causes her to lose the pigment, or the color, of her eye. Originally a dark brown, over the years the eye color is fading away to a purple-whitish hue with some brown spots.

This genetic issue does not effect her eyesight in any way; the cataracts do that. Chainsaw has developed cataracts in both of her eyes that prevent her from seeing much at all. This is not a problem for a seal due to their ultra-sensitive whiskers, or vibrissae, which you can also see pointing forward in the photo. Vibrissae are a much longer subject, so look forward to a blog on that topic in the near future. 'Til then enjoy looking at Chainsaw's sweet face.

#33: Naming Seals

What's In A Name?

Some may think that "Chainsaw" is an unusual name for a fur seal, much less a female fur seal. The reason behind the moniker is pretty simple though. Chainsaw was a stranded seal, which means she was found on a beach and was unable to take care of herself. In her case she was a very young pup when she was brought in. While being rehabilitated, or nursed back to health, she had the tendency to vocalize or "talk." When she did this she sounded like "a chainsaw revving up" so the nickname stuck. This video will give you a little taste of her vocal abilities:

#20: Mobile Seal

Make Mine To Go!




One of the most important aspects of our job as trainers is the training of husbandry behaviors. Husbandry behaviors are the behaviors that we use to take care of our marine mammal colony. A husbandry behavior can be something as simple as having the seal sit quietly while the trainer or veterinarian look them over to make sure they're in good condition. It might also be as involved as drawing blood, taking x-rays or performing an ultra sound. Having the seal enter a transport carrier is another example of a husbandry behavior. Doing so might be neccesary in order to move them to another part of the aquarium or to another facility entirely. Our three northern fur seals, Chainsaw, Ursula and Cordova are trained to enter a large kennel, turn around and allow the trainer to close the door. Behaviors like the kenneling that you see Chainsaw doing in this video are done regularly so they stay sharp in case we need them.

#11: Photo Matchup

Is that the same seal?


Northern fur seals have one of the densest fur coats in the world. There are up to 300,000 hairs per square inch on their bodies. Here are two pictures of the same fur seal, Chainsaw, when she is dry and wet. They look incredibly different sometimes. When they are dry they are so soft and fuzzy, when wet they're smooth and sleek.
