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).
Pigeye shark
The pigeye shark is a largely solitary animal, though occasionally several individuals may be found at the same location. In the Mozambique Channel, it outnumbers the bull shark on the east side while the opposite is true on the west side, suggesting there may be competitive exclusion between these similar species. Parasites documented from the pigeye shark include the myxosporean "Kudoa carcharhini", the copepods "Pandarus smithii" and "P. cranchii", and the tapeworms "Callitetrarhynchus gracilis", "Cathetocephalus" sp., "Floriceps minacanthus", "Heteronybelinia australis", "Otobothrium australe", "O. crenacolle", and "Protogrillotia" sp. Young pigeye sharks are potentially vulnerable to predation by larger sharks. The natural mortality for juveniles in Cleveland Bay has been measured at no more than 5% per year; this rate is comparable to that in juvenile bull sharks, and is much lower than in juvenile blacktip sharks ("C. limbatus") or lemon sharks ("Negaprion brevirostris").
