Cookiecutter sharks (Isistius brasiliensis) are known to attack a wide array of large animals including pelagic fishes, cetaceans, and pinnipeds. Here we add another top predator, the white shark (Carcharodon carcharias), to the list of potential victims. A subadult male white shark off Guadelupe Island, Mexico, was observed with a fresh cookiecutter shark bite next to its mouth, as well as a second crescent-shaped scar. A subadult male white shark was tracked in the same location and showed diel changes in depth, with the shark occupying shallow water (<50 m) at night, which may be when white sharks overlap with the vertical distribution of cookiecutter sharks. This further indicates that the majority of co-occurring marine top predators can be targeted by cookiecutter sharks.

    This is very interesting. Very nice paper, thank you for posting.
    This is the GWS capital of the wolrd for diving to take pictures. Clear view and waters.
    A small cookiecutter shark attacking a Great White, at least 10 times the size of himself. That is something to watch forever..
