Predatory tunicates (Megalodicopia hians) are tunicates which live anchored along the deep sea canyon walls and seafloor, waiting for tiny animals to drift or swim into their hood-shaped mouths. Looking something like a cross between a jellyfish and a Venus Flytrap, its mouthlike hood is quick to close when a small animal drifts inside. Once the predatory tunicate catches a meal, it keeps its trap shut until it is ready to eat again. They are known to live in the Monterey Canyon at depths of 200-1,000 m (656-3,281 ft).
