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).
Lake Salvador
Young Bull Sharks have been known to prefer low salinity, or brackish water, and in 2015 one was found in the lake. A Louisiana Department of Wildlife and Fisheries Marine Fisheries Biologist stated that bull sharks are one of the more aggressive shark species worldwide. Biologist manager Shane Granier stated "It’s not necessarily a common occurrence, but it’s not unheard of (to find sharks in the lake),".
