The Leopard Shark
Leopard Shark (Triakis semifascicata)Family Carcharhinidae (requiem sharks).The Leopard Shark (Triakis semifascicata) is in the Family of Carcharhinidaes (requiem sharks). Carcharhinidaes are the largest family of sharks in numbers. This family consists of bull sharks, sandbar sharks, tiger sharks, great blue sharks and more. The Leopard shark (Triakis semifascicata) grow to 7 feet and are heavily marked with black crossbars and blotches. Their teeth are short, broad and triangular shaped. The Leopard sharks (Triakis semifascicata) are active, fast sharks. They are nomadic, schooling sharks that roam inshore sand flats and rocky areas. They are known to feed on soles, bivalves, crustaceans, and other small bottom dwelling fish.Sharks have been around for 400 million years and out of that 400 million years about 100 million years the sharks and their close relatives have been closely unchanged in appearance. There are about 900 species of sharks and their close relatives. There are about 400 species of sharks and more are been found and added to the list. What makes a shark a shark? First it's skeleton is made of cartilage, which is lighter, tougher, and more flexible than bone.
Sharks have a bad reputation as bloodthirsty killers. On the other hand, with the increasing scarcity and rising price of many food fishes, especially for United States consumers, shark meat is itself now selling at prices comparable to those for traditional table fishes. Going against the popular image, the dorsal fins rarely project above water when the fish are close to the surface. Others species of sharks are viviparous. The most interesting difference is called the Ampoules of Lorenzini, which detect faint electrical currents from other fish. Eugenie Clark discovered that the Moses Sole from the Red Sea makes its own shark repellent. Unlike bony fishes, which usually spawn in great masses of tiny, immature young, most sharks produce large, well-developed offspring numbering, at the most, 100 to a litter. Many people begin to like and admire sharks as they learn about them. When the Moses Sole is attacked, it secretes a milky, toxin ooze out of it's skin and the shark will spit it out. Embryonic development takes more than six months. They have strong digestive enzymes and a specialized epithelial fold that spirals the length of the small intestine, enabling the fishes to absorb a great diversity of foods. Sharks are particularly sensitive to sounds of low frequency and have fine directional hearing.
