7. Sea Cucumber
An ocean-floor dwelling creature, Sea Cucumbers have two admirable abilities. First, they can literally spill their guts when threatened. Their insides are sticky and are meant to trap the attacker. Second, Sea Cucumbers have a compound in their tissue called collagen, which can change from liquid form to solid form and back again. This ability allows them to liquefy their bodies and pour themselves into a crack in a rock where they then solidify again.
