Astronesthes sp. (2008) is a stareate from the depths of the Antarctic Ocean south of New Zealand. It attracts small prey using the glowing red tip of a long black barbel on its chin as a lure.
The fish grows to a length of 21 centimetres (8.3 in). The mouth of the fish is filled with sharp, needlelike, curved teeth. The skin is delicate, and when trapped in a net, scientists abrased a specimen's skin retrieving it. Lining the belly of the stareater are tiny black dots, which serve as a type of light organ.
