This is the grandest aquarium in the Caribbean, a project funded during the Balaguer administration that caused great controversy, opponents claiming "the people's money" could be better spent elsewhere, perhaps on public schools, hospitals, and housing. Nonetheless, el presidente wanted a grand aquarium and continued to press for funds.

Misspent money or not, the results are spectacular. At one point you can take an underwater corridor under a Plexiglas tank, watching sharks, barracuda, and other ferocious-looking big fish glide by over your head. The exhibits are in Spanish only so you may not know the English names of some of the weirder denizens of the deep. You'll surely recognize a manatee. Lesser known might be the endangered slider turtle, part of a breeding project of the aquarium hoping to save this species from extinction.
