Horn Sharks [Heterodontus]

Description

Heterodontus is a genus within the family Heterodontidae, commonly known as horn sharks due to the distinctive horns in front of each dorsal fin, which are more prominent in some species than others. These sharks are distinguished by their stout bodies, pig-like snouts, and a unique set of teeth that includes small, sharp front teeth for grasping prey and flat molar-like teeth at the back for crushing. They are bottom-dwelling sharks, found in the Pacific and Indian Oceans, ranging from shallow intertidal zones to deeper continental shelf areas. Their diet mainly consists of invertebrates and small fish. Horn sharks are known for their distinctive egg cases, which are spiral-shaped and often attached to seaweed or rocky substrates. Despite their slow-moving nature, they are capable of quick bursts of speed when threatened or while hunting. Heterodontus species exhibit a variety of colorations, typically camouflaged to blend with the ocean floor, aiding in their ambush predator lifestyle.
