Galeocerdo Productus
''Galeocerdo'' is a genus of ground shark. Only a single species, ''G. cuvier'', the tiger shark, is extant. The earliest fossils date back to the early Eocene epoch, (Ypresian), around 56–47.8 Million years ago. While historically considered a member of the requiem shark family Carcharhinidae, it is currently considered to be the only member of the family Galeocerdonidae. While this genus was historically considered diverse, including 21 extinct species, morphometric analysis conducted in 2021 suggested that the diversity of the genus included only 5 extinct species (including the Eocene †''G. clarkensis'' and †''G. eaglesomei'', Oligocene-late Miocene †''G. aduncus'', Miocene †''G. mayumbensis'', and Pliocene †''G. capellinii'') much lower than previously assumed. The oldest fossils of the extant ''G. cuvier'' date to the middle Miocene. Species Species historically considered valid in the genus ''Galeocerdo'' include: * †''Galeocerdo aduncus'' * †''Galeocerdo ...

Galeocerdo Cuvier
The tiger shark (''Galeocerdo cuvier'') is a species of ground shark, and the only extant member of the genus ''Galeocerdo'' and family Galeocerdonidae. It is a large apex predator, with females capable of attaining a length of over . Populations are found in many tropical and temperate waters, especially around central Pacific islands. Its name derives from the dark stripes down its body, which resemble a tiger's pattern, but fade as the shark matures. The tiger shark is a solitary, mostly nocturnal hunter. It is notable for having the widest food spectrum of all sharks, with a range of prey that includes crustaceans, fish, seals, birds, squid, turtles, sea snakes, dolphins, and others, even smaller sharks. It also has a reputation as a "garbage eater", consuming a variety of inedible, man-made objects that linger in its stomach. Tiger sharks have only one recorded natural predator, the orca. It is considered a near-threatened species because of finning and fishing by humans. ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
