When hunting prey, the superpower of invisibility no doubt comes in handy.
One species that has been successful in the mastery of self-concealment is the angel shark, notes the BBC.
The bottom-dwellers evade detection by settling their flat, sand-colored bodies into the similarly colored ocean floor.
There, they wait until an unsuspecting creature happens by, then quickly approach and strike.
Once pinned by the sharks' needle-like teeth, there is little chance the target will escape.
While the art of camouflage has served the angel shark community well as far as securing meals is concerned, it has done little to protect it from the fishing industry.
Over the past decades their numbers have been significantly depleted, making them among the sea's most at-risk species.
