White teatfish (Holothuria fuscogilva), Ras Muhammad National Park, Red Sea, Egypt. This species of sea cucumber, also known as white teeth, is found in shallow waters near islands and around coral reefs in the tropical waters of the Indo-Pacific ocean. Juvenile cucumbers live in shallower waters (such as inter-tidal zones) and then migrate to deeper waters as they mature. Adult cucumbers weigh between 2.4 and 4 kilograms. They are oval in shape and have a firm texture. This species cucumber has lateral papillae (teats) which are often buried in the sand. As it's consumed as a food and is part of a large commercial fishery across its range, it was listed as vulnerable on the IUCN Red List in 2010 due to overfishing.
