BLUNTNOSE SIX GILL COW SHARK Highly unusual tooth formation. The bluntnose sixgill shark, often simply called the cow shark, is the largest hexanchoid shark, growing to more than 5.4 m. (18 feet) long. Many of its relatives are extinct. The living species that are closest genetically include the dogfish, the Greenland shark, as well as other six- and sevengilled sharks. There are more closely related relatives in the fossil record than living species. Some of the shark's relatives date back to 200 million years ago. Although sluggish in nature, the bluntnose sixgill shark is capable of attaining high speeds for chasing and catching its prey. Because of the bluntnose sixgill shark's large and diverse range they have a wide variety of prey items. Their diet consists of a variety of mollusks, crustaceans, Agnathans (which is a family consisting of hagfish), and sea lampreys. They also dine on Cape anchovies, Pacific salmon, various species of hake. THESE SHARKS ARE NOT CAUGHT FOR THEIR JAWS.

The jaws teeth are sold as a collectible to recycle 100% of the shark.
