One of world's weirdest shark species. Learn facts about the cookie cutter shark that bites whales, deep sea fish, and even submarines. Did you know that there is a shark that is also classified as a parasite. Parasites by rule hurt their prey but don’t kill them. The only parasite in the shark family. They average 20 inches long, about the length of the average ferret and are one of the smallest sharks in the world, the smallest being the dwarf lantern shark of Colombia and Venezuela. The cookie cutter shark used to be called the cigar shark and it’s pretty easy to see why. So where did the name cookie cutter shark come from? First a little about its lifestyle and it will all become clear. They live in the deep warm coastal waters, near islands, around the equator. I don’t mean kind of deep. These guys spend their days at depths equal to that of the Titanic Wreck. At night they come to the surface to feed, , and they have one of the best evolutionary fish lures in the world. Like many deep sea creatures they are bioluminescent. Their bellies are covered by photophores which emit a greenish glow that looks like a smaller fish to anything below it. Their bioluminescence is so strong that they’ll continue to glow up to 3 hours after they die. As for the hunt their technique is to wait for something to try and eat them from below, or just pass by, then they whip around and form a tight suction with their mouth on the attacker. Then they turn in a circle and carve out a chunk of the animal and swallow it before letting go. The result is an almost perfectly round crater looking hole resembling one made by a cookie cutter, hence the name change from cigar shark. They aren’t choosy about their victims either. They attack seals, whales, dolphins, large fish, mega mouth sharks, and even nuclear submarines. There have been a few recorded cases of cookie cutter sharks taking a bite out of the rubber sonar domes of passing submarines. Sometimes inflicting enough damage to cause an oil leak and send them back to port. But don’t worry there have been very few recorded attacks on humans, since they only come up from the depths at night and they’re so small they’re not deadly. They’re parasites remember.

edit- that is talking about a different incident though, not the cookiecutter one in 2009
""An incident at Haena, Kauai, on November 25, 1995 was misdiagnosed as a shark bite. The wound was initially attributed to a cookiecutter shark, but a tooth fragment recovered from the victim was determined not to have come from a shark, based on information from the International Shark Attack File.""
Nkt a pet animal but I understand.
