The pool is very small and impossible to photograph due to horrible glare off of the glass. The best sea otter exhibit that I've ever seen is at the Minnesota Zoo, in the new Russia's Grizzly Coast area. The tank at San Diego Seaworld is quite large, and I've also seen sea otters at Monterey Bay Aquarium, Georgia Aquarium, Vancouver Aquarium, Seattle Aquarium, Shedd Aquarium, Point Defiance Zoo & Aquarium and probably a couple more places that I can't recall off of the top of my head. Minnesota's is the best, and Pittsburgh's is simply average.
