Coelacanths are deep-sea fish and are typically found at depths of 100 to 700 meters (330 to 2,300 feet).
Coelacanths are known for their unique features, such as a hollow, oil-filled spine and a rostral organ in the snout. They have muscular fins that can be used for walking on the ocean floor. Coelacanths are nocturnal and feed on fish and cephalopods. They have a slow reproductive rate, with females giving birth to a small number of live young.
