Spinner Shark

What this shark is

Typical requiem sharks are streamlined, with two dorsal fins, an anal fin, five gill slits, and a distinct nictitating lower eyelid. Color is often gray to bronze above with a pale underside.

Where it lives

Requiem sharks occupy tropical and warm-temperate seas worldwide, from coastal estuaries and reefs to outer shelves and open ocean. Individual species may be strongly coastal, strongly pelagic, or somewhere in between.

This family uses an unusually wide span of habitats, including surf zones, mangroves, coral reefs, seagrass flats, shelf edges, and oceanic waters.

Why it is notable

Some of the best-known large sharks in tropical waters belong to this family, so human encounters do occur. Even so, fishery pressure, bycatch, and habitat loss usually matter more than direct conflict.

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.
