Octopus to Color
One of the Seattle Aquarium's favorite exhibits is the Giant Pacific Octopus. They're surprisingly fast movers in open seawater.
My father loved showing us how octopus can rapidly change their colors, they're quite intelligent and enjoy solving food puzzles.
The Seattle Aquarium left a clear jar in the tank, and the octopus would dive into the glass jar to "hide" when we came too close.
