Lost shark
Carcharhinus obsoletus
The lost shark (Carcharhinus obsoletus), previously known as the false smalltail shark, is a possibly extinct species of requiem shark (family Carcharhinidae). It is known only from the Western Central Pacific Ocean, in the southern South China Sea.

In human culture
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.
