IDENTIFICATION VERDICT

These teeth overlap in both broad form and edge treatment. Root proportions, jaw position, size, age and locality must carry more weight than silhouette alone.

FIELD MARKNurse sharkZebra shark
Signature

Small tooth with a central cusp flanked by several smaller cusplets on a broad base.

Small central cusp bordered by two smaller cusplets on a compact broad base.

Crown

Jaw variation

Similar small multi-cusped teeth occur in both jaws and form gripping-crushing rows.

Small central cusps and lateral cusplets repeat in both jaws.

Habitat

Warm shallow reefs, ledges, seagrass and sandy bottoms.

Indo-Pacific coral reefs and sandy bottoms.

Diet

Crustaceans, mollusks, fishes and rays taken by suction.

Mollusks, crustaceans, small fishes and sea snakes.

Shark size

Commonly 2.2–3 m (7–10 ft).

Usually 2–2.5 m (6.5–8 ft).

Bite force

No reliable species-specific value is established; bite force changes with body size and bite point.

No reliable species-specific value is established; bite force changes with body size and bite point.

Fossils

Fossil teeth are reported, but isolated teeth may only be identifiable to genus or family.

Carpet-shark teeth occur, but isolated species attribution is difficult.

NURSE SHARK TRAP

Small teeth are easily damaged or mismeasured; a close macro photograph is especially important.

ZEBRA SHARK TRAP

Carpet-shark teeth overlap strongly; associated jaws or provenance may be needed.
