CRESTED HORN SHARK FACTS

Description
Blunt head with a prominent ridge above both eyes. It has two tall dorsal fins that are each preceded by a stout spine. It is grey to brown with large dark blotches. Females are larger than males. Body size up to 150 cm.

Its diet consists of echinoderms, crustaceans, molluscs and small fishes. It is an egg-laying species (oviparous). Females lay dark brown spiralled egg cases that are usually seen attached by tendrils to seaweed. Young hatch from the egg case after about eight months at about 22 cm in length. The spine at the leading edge of the dorsal fins of juveniles may be sharp.
