Can't wait to see the new dolphin/manatee house when it open, it looks to be a huge improvement.
Although the dolphin pool will be an outdoor extension to the existing pool.
Define "quite a lot". There is no current Western institution keeping Amazonian Manatees, and afaik, only the Toba Aquarium keeps African Manatees. And "even" the numbers of zoos and other facilities keeping the different subspecies of the West Indian Manatee is limited.
