And sea otters. This particular otter was the first otter ever to be both born and reared in captivity. He came from Oregon, they told me.
As you continue through the gallery, you'll come upon this very unusual tank. It was basically two tanks, with a 4" tube between them. In this shot, they were training the octopus to travel through the tube by coaxing him with food on a hose.
Around the corner from the Giant Pacific Octopus, the floor started looking a little... cracked. It was in preparation for the next animals, who live in the polar regions. The floor was intended to look like ice chunks in the ocean. I thought it was pretty ingenious.
This brought you to the 5 Beluga Whales. And their massive tank. This tank was the second largest in the aquarium, as I recall. I never got an actual size. It did, however, house 5 Beluga Whales, so what would you expect?
