Sphyrna lewini (Scalloped Hammerhead) is a species of modern sharks in the family hammerhead sharks. They are listed as critically endangered by IUCN and in cites appendix ii. They are native to Mediterranean Sea, Atlantic Ocean, Indian Ocean, and Pacific Ocean. They are solitary, crepuscular carnivores. Individuals can grow to 430 cm. Reproduction is viviparous and iteroparous. They have parental care (female provides care). They rely on swimming and carcharhiniform to move around.

URI: http://eol.org/schema/terms/criticallyEndangered
Definition: A taxon is Critically Endangered when the best available evidence indicates that it meets \r\nany of the criteria A to E for Critically Endangered, and it is therefore considered to be facing an extremely high risk of extinction in the wild

URI: http://eol.org/schema/terms/CITES_II
Definition: Appendix II lists species that are not necessarily now threatened with extinction but that may become so unless trade is closely controlled. It also includes so-called "look-alike species", i.e. species whose specimens in trade look like those of species listed for conservation reasons. International trade in specimens of Appendix-II species may be authorized by the granting of an export permit or re-export certificate. No import permit is necessary for these species under CITES (although a permit is needed in some countries that have taken stricter measures than CITES requires). Permits or certificates should only be granted if the relevant authorities are satisfied that certain conditions are met, above all that trade will not be detrimental to the survival of the species in the wild. (See Article IV of the Convention)
