Horn shark

The Horn shark (Heterodontus francisci) is a species of shark recognizable by its distinctive brown color with darker spots. It is native to the coastal waters off the western North American coast, ranging from California, USA, to the Gulf of California in Mexico. This shark is characterized by a short, blunt head with high ridges above its eyes and two dorsal fins, each supported by a spine. It is not commonly kept in the aquarium trade, primarily due to its size and the specific requirements of its habitat.
