Old barnacle crusted crab
via @SeeThroughCanoe"Although they look creepy and dangerous, their 12 claws are not strong enough to hurt a person. And that crazy tail that looks like something meant to impale a human is just used to right themselves if they end up on their back. They don't have teeth either. They used to be considered a nuisance and an eyesore when they gathered in huge numbers on the east coast of the U.S. They were often used for fertilizer. Now we have come to realize their blue blood has valuable medical secrets to unlock and it is used in the detection of bacterial endotoxins in medical applications."
