Blunt nose six-gill shark
From Openwaterpedia
noun - The bluntnose sixgill shark, often simply called the cow shark, is the largest hexanchoid shark, growing to 4.8 m (16 ft) in length. This shark is one of the commonly studied deep-sea sharks due to students using bait (tuna or carrion) to do tests to see how deep-sea fish find their food in the lightless world of the deep sea.
