Feeding habits

Their prey is attracted to the shark by its glowing light. When the prey comes in to bite the shark, the fish is unexpectedly bitten by the shark. It latches on to its prey and with its razor sharp teeth it spins and cuts a "cookie shaped hole in its prey.


They are found in deep water at depths below 3,281ft (100m), during time hours. During the night cookie cutter sharks migrate vertically to the surface of the water to feed.
