Hugh's Aquarium Views Video Number 91
They may just look like fun antics but the behaviors that the mammalogists at the Aquarium of the Pacific train the otters to do all serve a purpose, even the cute ones. They allow the staff to build up a relationship of trust that allows them to very thoroughly check over the otter’s health and well-being.
In the video, you can see Mammalogist Erin checking out the fur and paws of Chloe the otter. And a little fun video editing makes it seem that Betty the sea otter is practicing a few martial arts at the beginning of the video while she is presenting her paw pads.
Fun with a purpose.
