The perfect shark

Sharks are obviously a big threat to us in the War on Animals. They lurk beneath the waves, they attack beachgoers at random more off America's shores than anywhere else and they have their own theme music.

But now it seems they are crossbreeding, possibly to form the perfect killing machine. A dead pregnant blacktip reef shark at the Virginia Aquarium was found to have an unusual looking unborn offspring. Veterinarians believe its father was not a blacktip reef shark.

We should all be thankful the shark was not born. Who knows what could have resulted from the unholy union?
