Careproctus cypselurus is a deep-sea fish from the snailfish family. It lives on the bottom of cold seas in the northern part of the Pacific Ocean and has a soft body without scales.
Careproctus cypselurus differs from other liparids with its soft body and a sucker on its belly. This fish is important as part of the food chain in deep seas and helps scientists understand life in conditions of high pressure.
Immature form that undergoes metamorphosis before adulthood.
