11. The Sea Cucumber
Get ready for another gross-but-useful superpower! The sea cucumber has evolved an unusual adaptation: it can liquify itself. Yes, like the T-1000 or Alex Mack, this oceanic creature can fit through tiny spaces and evade predators by ejecting its guts out of its butt. It's not classy, but it is effective, as evidenced by the sea cucumber's huge populations. Some species have developed even crazier defense mechanisms, such as shooting deadly poison, or spitting their net-like lungs out of their body to entangle predators (yes, you read that nightmarish scenario right). The upshot? DON'T MESS WITH SEA CUCUMBERS.
