Leopard sharks belong to the family, triakidae, which are hound sharks. The biome in which they live is called the marine biome. This species is found on the Pacific Coast of North America. They are distinctively marked with dark brown spots on a silvery gray background. Also, they have many small, sharp teeth equipped with points long enough to puncture the skin. The leopard shark is a very slim animal with a narrow head. Its reproduction is ovoviviparous (producing eggs that develop within the body and hatch within or immediately after extrusion from the parent) with up to 30 pups per litter. It may grow up to 6 feet, but it does range from being 3 to 6 feet long.
NOT a suitable fish for a home aquarium. Its not a question of whether its legal or not but if you can house a fish of this size.
