Biology and ecology edit
Although sluggish in nature, the bluntnose sixgill shark is capable of attaining high speeds for chasing and catching its prey using its powerful tail. Because of its broad range, it has a wide variety of prey, including fish, rays, chimaeras, squid, crabs, shrimps, seals, and other (smaller) sharks.[1] The bluntnose sixgill shark is therefore classified as a generalist species, and is less likely to be affected by scarcity in any one of its food sources.[2] The bluntnose sixgill shark can use a variety of techniques to attack potential food sources. It can protrude its upper jaw and utilize both sawing and tearing methods to manipulate its food. This variability in its feeding mechanisms could have contributed to its evolutionary success and global distribution.[3]
