To escape a vicious attack from a predatory bird, this crab snips off its injured claw to make a quick getaway.
Only a few humans have ever opted for self-amputation in order to escape from danger, but some animals do it all the time.
You probably already know that lizards can shed their tails. You may also have seen the viral video of a crayfish snipping off its own arm to escape being boiled alive.
