The deep water stingray ( Plesiobatis daviesi ) is a species of ray from the order Myliobatiformes . It is the only species of the monotypic family Plesiobatidae.
The habitat of deep-water stingrays is at a depth of 44 to 680 m. They are found above soft ground, where they feed on small fish, crabs, shrimps and lobsters, as well as octopuses and polychaete worms.
Its distribution area is the Indian Ocean between the Southeast African coast ( South Africa and Mozambique ) and southern India as well as the Pacific Ocean between India in the west and the Philippines in the east, between Japan in the north and Australia in the south. In 2003, specimens of Plesiobatis daviesi were observed at a depth of 650 m during an expedition to explore submarine canyons off Hawaii . The seas in the Indo-Pacific region between 33 ° north latitude and 33 ° south latitude are preferred.
Because of its way of life in deep and inaccessible areas of the continental shelf, the way of life of the deep-water stingray has not yet been well researched. Future deep-water expeditions will discover many previously undescribed creatures in these habitats, including perhaps other species of the deep-water stingray family.
