Common name: Bullhead sharks

The Heterodontidae family, commonly known as bullhead sharks, comprises a small group of benthic sharks characterized by their distinctive head shape and ridges above their eyes. They are generally small to medium in size and are known for their ability to crush shellfish, thanks to their specialized teeth. In the aquarium, they are a rare sight due to their size and specific requirements. They are not recommended for the average hobbyist, as they need large tanks with plenty of hiding spaces and a diet that reflects their natural predation on hard-shelled invertebrates.
