whale fall

Deep-sea bonanza

A whale fall is the carcass of a whale that has sunk to the ocean floor.

These massive deposits of organic matter create temporary ecosystems, sustaining deep-sea scavengers and specialized organisms for decades.

The term combines the animal with the sense of fall meaning descent: Scientists discovered a whale fall teeming with hagfish and bone-eating worms.
