Horn Shark
(Heterodontus francisci)
Population Status in the Wild: Near Threatened
The hornshark is a species of small, bottom-dwelling shark found along the rocky reefs and sandy bottoms of the eastern Pacific Ocean, primarily in the waters off California and Baja California, Mexico. It is named for the distinctive, horn-like protrusions on its snout, which give it a unique, rugged appearance. Horn sharks are relatively small sharks, typically growing to about 3 to 4 feet in length. Their bodies are stout and muscular, with a thick, spiny dorsal fin and a blunt, rounded head.
Horn sharks are primarily nocturnal and are known for their slow, deliberate movements. They feed on a variety of prey, including mollusks, crustaceans, and small fish. Using their strong jaws and sharp teeth, horn sharks are able to crush hard-shelled prey like crabs and snails, which form a large part of their diet. They are opportunistic feeders, often foraging in rocky crevices or the sand where prey can be found.
One of the most distinctive behaviors of horn sharks is their use of "nesting" sites, where they seek shelter during the day. They are often found hiding in caves, under rocks, or in other protected areas. During the breeding season, female horn sharks lay eggs in protective cases, which are sometimes called "mermaid's purses" due to their long, leathery appearance.
The horn shark is classified as Near Threatened due to concerns over habitat degradation and overfishing, particularly in some areas where they are targeted for their meat and fins. They are also vulnerable to the destruction of their coastal and rocky habitats.
Fun Facts:
The horn shark is often seen resting on the ocean floor during the day, coming out to feed at night.
The small spines in the dorsal fin of the horn shark are used for defense against predators.
Horn sharks are slow-moving sharks, but they can be surprisingly agile when hunting prey or navigating through rocky crevices.
