The Order Heterodontiformes is a small group of sharks commonly known as bullhead or horn sharks. They are distinguished by having heterodont dentition, meaning they possess different types of teeth adapted for crushing and tearing, allowing them to feed on hard-shelled prey such as mollusks and crustaceans. These sharks are generally small, slow-moving, and benthic, often inhabiting shallow coastal waters and rocky reefs. Heterodontiformes are oviparous, laying spiral-shaped eggs, and are mostly found in the Indo-Pacific region. They represent a primitive lineage of sharks, retaining several ancestral features compared to more modern shark groups.
