The Horn Shark is a small species of shark found primarily in the coastal waters of the eastern Pacific Ocean, particularly around the waters of California and Mexico. It typically grows to about 3.5 feet in length and is known for its distinctive, horn-like structures on its head, which help it blend into rocky environments. These sharks are primarily nocturnal and feed on small fish, crustaceans, and mollusks. They are bottom-dwellers, often found resting on the ocean floor during the day. The Horn Shark is not considered dangerous to humans and is often kept in aquariums due to its manageable size and unique appearance.
