Range of horn shark (in blue) | ||||||||||||||||
Its habitat includes rocky reefs, kelp beds, sand flats, crevices, and caverns in a depth range from 2 to 150 m. Adults tend to return to the same resting spot every day. It feeds on invertebrates, primarily sea urchins, crabs, probably abalone, and other fish.
The horn shark is oviparous, laying 12–14 cm (5 inches) long kelp-colored spiral-shaped eggs that may float up on beach shores.

conservation status of a species is an indicator of the likelihood of that species continuing to survive either in the present day or the future. Many factors are taken into account when assessing the conservation status of a species: not simply the number remaining, but the
