An incredible adapted species, this fish is camouflaged to mimic a dead leaf, both in a body shape and pattern. It can change color to match its surroundings and has a projection from its bottom lip that resembles a leaf stalk. When hunting, it stalks its prey in a head-down stance, appearing to drift towards its like a dead leaf drifting in a current. In reality, the fish is propelled by tiny movements of its transparent fins. When it strikes at an item of prey the entire mouth protrudes outwards, forming a large tube into which the prey is sucked, usually head first. This happens so quickly that it is often difficult to see. In this way it can swallow prey almost as big as itself.
