Approximately 500 fish species live around the coral barrier, 200 sponges and many different varieties of mollusks, gorgonias, shellfish and other marine animals.

More specifically, we find formations of coral stars and coral cerebro, feathery gorgonias and numerous fish such as loros, barberos, roncos, chapas, stone bass, red snapper and many shellfish such as lobster.

The presence of trigonias, considered living fossils and the oldest in the Antilles is an important attraction of the region.
