Today’s FOTD is brought to you by the letter C, which is for cookie…and cookiecutter shark.
Unlike most of the other sharks I’ve written about so far, the cookiecutter shark is a relatively small shark; they only reach about 20 inches in length. Like some other sharks, such as great white sharks, female cookiecutters are larger than their male counterparts.
Despite their small size, these sharks still have quite a bite. They latch onto their prey and create suction with their large lips. Then they use their powerful jaws and many teeth to carve a circular chunk of flesh out of the unlucky victim. (Get it? Like a carnivorous, marine cookiecutter?)
Cookiecutter sharks attack large fish like tuna or even whales and dolphins; the prey usually survives the attack but the telltale round scar remains. They are also bioluminescent; they have a patch on their bellies that glows in the dark, deep waters where they live. They use their bioluminescence to attract potential prey.
See you tomorrow for another shark FOTD and I hope you’re enjoying Shark Week as much as I am!
