The predatory tunicate (Megalodicopia hians), also known as the ghostfish,^[2] 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 is actively predatory. Its mouthlike siphon is quick to close whenever a small animal such as a crustacean or a fish drifts inside. Once the predatory tunicate catches a meal, it keeps its trap shut until the animal inside is digested. They are known to live in the Monterey Canyon at depths of 200–1,000 metres (660–3,280 ft). They mostly feed on zooplankton and tiny animals, and their bodies are roughly 5 inches (13 cm) across.^[3]

Predatory tunicates are hermaphrodites, producing both eggs and sperm which drift into the water. If there are no other tunicates nearby, they can self-fertilize the eggs.^[4]
