This sea cucumber—held by Sadie Mills of New Zealand's National Institute of Water and Atmospheric Research—is known as a sea pig.

Mills and colleagues collected the organism, among more than 30,000 animals, during a marine census of southern Antarctica in early 2008.

Sea cucumbers are part of a group of marine animals that inhabit the seafloor, including sea squirts, sea stars (starfish), sea slugs, corals, clams, sponges, and urchins.
