Bathysaurops

Bathysaurops is a genus of deep-sea fishes belonging to the family Bathysauroididae. These fishes are characterized by their elongated bodies, large heads, and small, underdeveloped eyes. They possess a unique sensory system, with rows of pores along their bodies that are thought to detect vibrations in the water. Bathysaurops species are found in the abyssal and hadal zones of the world's oceans, inhabiting depths ranging from 2,000 to 6,000 meters. Their diet consists primarily of small invertebrates and crustaceans. Little is known about the reproductive habits of Bathysaurops, though they are believed to be oviparous, laying eggs on the seafloor. The genus currently contains only one recognized species, Bathysaurops pectoralis, which was first described in 1904. These fishes are rarely encountered due to their deep-sea habitat, making them a subject of ongoing scientific interest for understanding life in extreme environments.
