Heterodontidae

The Heterodontidae family, commonly known as bullhead sharks, comprises about 11 species of sharks belonging to the genus Heterodontus. These sharks are characterized by their broad heads, short snouts, and small mouths. They are found exclusively in the tropical regions of the Pacific and Indian Oceans, as well as the eastern Pacific from California to the Galapagos Islands.1

Bullhead sharks are harmless to humans and primarily feed on mollusks, crabs, and sea urchins. Their teeth are adapted for crushing and grinding. Most species reach about 1 meter (3.3 feet) in length, with some, like the Mexican hornshark and the Port Jackson shark, growing larger. Unlike many other shark populations, most bullhead shark species are considered to be of least concern for conservation.1
