Caribbean Sea
Marine biota in the region have representatives of both the Indian and Pacific oceans which were caught in the Caribbean before the emergence of the Isthmus of Panama four million years ago. In the Caribbean Sea there are around 1,000 documented species of fish, including sharks (bull shark, tiger shark, silky shark and Caribbean reef shark), flying fish, giant oceanic manta ray, angel fish, spotfin butterflyfish, parrotfish, Atlantic Goliath grouper, tarpon and moray eels. Throughout the Caribbean there is industrial catching of lobster and sardines (off the coast of Yucatán Peninsula).
Dominica
The Caribbean Sea offshore of the island of Dominica is home to many cetaceans. Most notably a group of sperm whales live in this area year-round. Other cetaceans commonly seen in the area include spinner dolphins, pantropical spotted dolphins and bottlenose dolphins. Less commonly seen animals include killer whales, false killer whales, pygmy sperm whales, dwarf sperm whales, Risso's dolphins, common dolphins, Atlantic spotted dolphins, humpback whales and Bryde's whales. This makes Dominica a destination for tourists interested in whale-watching.
