Careproctus bathycoetus is a deep-sea fish from the family of snailfishes. It lives on the bottom of the northern part of the Pacific Ocean at a depth of several kilometers.
Careproctus bathycoetus is distinguished by its gelatinous body that withstands enormous water pressure. This fish is important for the deep-sea ecosystem because it transfers energy between different layers of the ocean.
