The Pacific sleeper shark (Somniosus pacificus), also known as the "sleeper shark", is a shark living in waters off Antarctica and is one of two creatures (along with the sperm whale) that hunt giant squid and colossal squid for food, as research on the stomach contents of this shark has shown. Scientists are unsure how the 7 meter (23 feet) shark can devour its 12-14 meter (39-46 feet) prey (another possibility is that the shark only feeds on the squids' carcasses, rather than hunting them).
