Snaggletooth shark

The snaggletooth shark is Hemipristis elongata, a member of the weasel-shark family Hemigaleidae. It is the only living species in the genus Hemipristis. ([NCBI research](https://pmc.ncbi.nlm.nih.gov/articles/PMC7799708/))

Its feeding apparatus includes large, serrated upper teeth and long, curved lower teeth, giving the jaws a visibly uneven appearance. Those cutting teeth suit a shark that catches and tears animal prey rather than filtering small organisms from the water.

It occurs across the Indo-West Pacific, including parts of the Indian Ocean and the Red Sea. Scientific records place it in coastal and continental-shelf waters from near the surface to at least 132 metres deep. ([Feeding morphology study](https://pmc.ncbi.nlm.nih.gov/articles/PMC7812129/))

Hemipristis elongata is largely fish-eating, with fishes, rays, and other marine animals among its reported prey. Its long mouth, powerful jaws, and serrated teeth are adapted for cutting that kind of prey.
