Characterized by darkness and intense pressure, the ocean's hadal zone seems uninhabitable, yet dozens of unique organisms call it home.

A new study highlights one of those species -- the newly named Dulcibella camanchaca. This crustacean is the first large, active predatory amphipod from these extreme depths.
