Underwater viewing is cool.Is there any "strange" underwater viewing you know?I mean, except hippos,crocs,penguins,seals,and otters those "normal" one, any weird one you have known?I know that Zurich(?) have a elephant pool for underwater viewing, but are there other great one?
Pessac/Bordeaux has introduced a water tank for Jaguar feeding talks. Chester's Tigers have an underwater view point, but I haven't seen them in there myself
There is a pretty damn good underwater viewing window for the elephants at Zoo Leipzig; I recorded a few videos of the elephants bathing when I visited in 2014:
Australia Zoo has underwater viewing for tigers, and every platypus exhibit I know of has underwater viewing.
Capybara - Reid Park Zoo (though they are currently moved to the guanaco yard) Jaguar - Woodland Park Zoo, Zoo Miami (plus a couple others) Grizzly Bear - Cheyenne Mountain Zoo (plus those mentioned earlier) Tiger - San Diego Safari Park, maybe Bronx Zoo? Reticulated Python - Wildlife World Zoo White Alligator - Wildlife World Zoo Diving Ducks and their relatives (various species) - San Diego Zoo, Alaska Sealife Center
The more unique underwater viewing opportunities I've seen are for tigers at Hogle Zoo (and he was very active when I visited) and anaconda at Como Zoo. Henry Doorly Zoo had raccoons in a mixed enclosure with juvenile alligators that had underwater viewing, although I didn't see the raccoons swimming.
Shedd Aquarium also has it for anacondas. I have seen underwater viewing for various turtle species (even tortoises!) Shedd also has underwater viewing for Caiman Lizards. Lincoln Park has underwater viewing for various diving ducks.
I've took this pic in my home Saragossa Fluvial Aquarium. In fact, the monitor have a large underwater area but very little (and wet) emergent land to rest :-(
