This scientific paper details the first documented attack on a live human by a cookiecutter shark, named so because it uses its large bottom jaw teeth to bite out a cookie-cutter shaped piece of flesh from its victim. In this particular case from 2009, the shark first tried to carve out a piece of the 61-year-old man’s chest, and then was more successful in getting a piece of his leg, while he attempted to board a support kayak. There are pictures of the wound in the paper, looking quite gruesome when fresh, but then later turned out to heal quite fine. Via treehugger.com.
