Overview

This shark belongs to the houndshark family, a broad group of shelf and nearshore species with a practical coastal build. In PocketShark, expect a benthic-to-near-benthic predator rather than a flashy pelagic specialist. Houndsharks are usually slender to moderately built coastal sharks with two dorsal fins, an anal fin, and a generally understated gray-brown appearance. Houndsharks occupy temperate, subtropical, and tropical seas around the world, most often on continental shelves and in nearshore habitats.

Typical habitats include sandy bays, estuaries, rocky shelves, kelp-fringed coasts, reefs, and upper-slope margins.

Added from the World Register of Marine Species (WoRMS).

Why it matters: The family includes both egg-laying and live-bearing species, which is a useful reminder that shark reproduction does not follow one simple rule.

How it differs from similar sharks

Family: Triakidae

Compare it against Arabian smooth-hound, Florida smoothhound, and Gulf smoothhound.

Why it is notable

They are not major problem sharks for people. Fisheries pressure and nursery habitat loss are the more common concerns.

Species-level taxonomy was verified from Sharkipedia's current species list and taxonomy workbook. In this pass, the narrative fields are cautious family-level placeholders synthesized from broad shark references, chiefly the FAO Sharks of the World catalogue, because a stronger multi-source species-level synthesis was not assembled here without risking invented detail. Replace this with a direct species-level synthesis before publication in the app.
