The largest specimens in the family Sand-cone-toothed Sharks are 4.5M/289Kg in size. Compared with the more common cone-toothed sharks, the first dorsal fin is more forward and the second dorsal fin is slightly smaller than the first dorsal fin. Because of its small and dense dentition and the largest number of teeth in the family, it is also known as Smalltooth Sandtiger Shark, which is distributed at global temperature. Belt and subtropical waters, the distribution area is relatively scattered, usually found in the 13-880M depth of the continental shelf uphill and seamounts near the sea area, its maximum habitat depth can reach about 2000 M, its appearance varies according to the origin of the population, ferocious sand cone-toothed shark character is not ferocious, this species mainly feeds on small fish, crustaceans and cephalopods, at present we still know little about this species.
IUCN currently assesses its population as VU. Severe conical sharks are sometimes caught by Gill nets, bottom trawls and longline fishing. Their livers can provide high-quality cod liver oil. However, their overall economic value is not high and they are often discarded after capture. At present, their populations are seriously threatened by overfishing, habitat degradation and marine pollution.
