Smalltooth Sand Tiger

Very little is known of the biology and behavior of the smalltooth sand tiger. It is an active predator of benthic bony fishes, invertebrates, and cartilaginous fishes. This species is thought to be ovoviviparous with oophagous embryos like other mackerel sharks. In contrast to its formidable size and appearance, this shark is harmless, having never been known to behave aggressively towards humans. There is concern that its numbers are declining due to human activities in the Mediterranean and elsewhere, though existing data is inadequate for a full assessment of its conservation status.

They usually inhabit deepwater rocky habitats and has been caught down to a depth of 880 m.

It consists of bottom-dwelling bony fishes such as rockfish, invertebrates and possibly marine isopods, and cartilaginous fishes including rays and chimaeras.

This species is presumed to be ovoviviparous as in other mackerel sharks. The size at birth is estimated to be 1.0–1.1 m.
