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).
Lost shark
The lost shark ("Carcharhinus obsolerus"), previously known as the false smalltail shark, is a very rare species of requiem shark (family Carcharhinidae). It is known only from the Western Central Pacific Ocean, in the southern South China Sea. Only three specimens of this species are known, found in Borneo, Vietnam, and Thailand, all of which are over 80 years old. The specimens were originally tentatively assigned as belonging to the smalltail shark ("C. porosus"), but a number of subtle morphometric differences revealed that they belonged to a new "Carcharinus" species, referred to as "Carcharinus" sp. A. It differs from other "Carcharinus" species by the relative position of the second dorsal and anal fins, as well as its low vertebral count.
