The teeth are in several series; the upper jaw is not fused to the cranium, and the lower jaw is articulated with the upper. The details of this jaw anatomy vary between species, and help distinguish the different elasmobranch clades. The pelvic fins in males are modified to create claspers for the transfer of sperm. There is no swim bladder ...
Carcharhinus sealei found in Malaysia, its similar markings on the second dorsal fin cause its morphological identification to overlap with C. tjutjot. Initially thought of as C. dussumieri, it was later identified as a distinct species in 2012 [5] by morphological characteristics such as vertebral counts, dorsal and pectoral fin shape, and fin colouration.

The great white shark had never been successfully held in captivity for long periods of time until September 2004, when the Monterey Bay Aquarium successfully kept a young female for 198 days before releasing her.

The megamouth shark is an extremely rare species of deepwater shark, and the smallest of the three filter-feeding sharks. Since its discovery in 1976, only a few megamouth sharks have been seen, with 55 specimens known to have been caught or sighted as of 2012, including three recordings on film.
Extinct species within this genus lived from the Cretaceous period to the Quaternary period (from 99.7 to 0.012 Ma). Fossils have been found all over the world, especially in the Miocene and Oligocene sediments of Europe, the United States and Australia, in the Eocene of Egypt, Europe and the United States, as well as in the Cretaceous of Australia, Canada, the United States, Europe and Africa ...
