Cookiecutter Shark (Isistius brasiliensis)

The Cookiecutter teeth to body size is larger than any other shark in the ocean. Its also has massive eyes that are used to spot prey in the dark depths. This deep sea fish is a hit and run type predator. It will actually attract bigger fish to it using its bio-luminescent.  Once the fish gets close enough it attacks and rips out a piece of flesh with its razor sharp teeth. Just check out this video below to see what this creature can do to a dolphin...










The Cookiecutter Shark or Isistius brasiliensis is a small shark that grows to about 50cm (20") in length.. The shark's body has a cigar shape and is sometimes referred to as the Cigar Shark. This shark is also called the Luminous Shark because of its use of bio-luminescent. Found at depths of 1,000 m or 3,300 ft the Cookiecutter Shark is rarely seen by humans so little is known about their reproductive habits.

  3. I read that once a cookie cutter shark forced an atomic sub to return to base, because it bit off a piece of the anecoic surface that renders the sub invisible to sonar! They identified the species by a tooth that got stuck in the rubber-like surface.

  6. They suction on to their prey and then use their bottom teeth to scoop out a near perfect circle like an ice cream scoop. Their bite scars have been seen on seals, dolphins, and even Great White Sharks. To the best of my knowledge, there has only been one human attacked by this shark, a long distance swimmer near Maui. (I find this and the Ghost Shark to be the most interesting Sharks)
