The predatory tunicate (Megalodicopia hians), also known as the ghostfish, is a species of tunicate which lives anchored along deep-sea canyon walls and the seafloor. It is unique among other tunicates in that rather than being a filter feeder, it has adapted to life as an ambush predator. Its mouth-like siphon is quick to close whenever a small animal such as a crustacean or a fish drifts inside.
