Family HETERODONTIDAE


Common name: Bullhead Sharks, Horn Sharks, Hornsharks, Port Jackson Sharks

Silhouette

Summary:
Bottom-dwelling shallow water sharks with two dorsal fins, each beginning with a large spine, an anal fin, a large head with distinctive ridges over the eyes and a small terminal mouth. The small sharp teeth at the front of the jaws differ markedly from the large crushing molars at the rear of the jaws - perfect for feeding on hard-shelled invertebrates.

Horn sharks are nocturnally active and feed on a range of benthic invertebrates. Females lay large spiral-shaped egg cases.
