Coffin fish are flabby bottom-dwelling fishes that occur in deep waters around the world. They can walk along the sea floor on short leg-like fins. These fish often come up in the nets swollen into a ball. Like the pufferfishes, they can swallow large amounts of water to inflate themselves, presumably making it harder for predators to bite into them.
