South China cookiecutter shark

The South China cookiecutter shark, Isistius labialis, is a sleeper shark of the family Dalatiidae found in the South China Sea at depths down to 520 m. It is named from its feeding style which often creates perfect "cookie-cutter" shaped plugs in the skin of large marine mammals and large sharks.

Reproduction is aplacental viviparity in the same way as great white sharks.
