The Hyuga fanray (Platyrhina hyugaensis) is a type of ray of the family Platyrhinidae. It is an endemic species of southern Japan and inhabits shallow region at the depths of 1–50 m (3 ft 3 in – 164 ft 1 in). The population of this ray are decreasing due to continuous human exploitation.
Description
The Hyuga fanray can be differentiated from its congeners because of numerous characteristics, including a pair of thorns on anterior part of scapular section, a row of thorns on mid-dorsum of tail, and dermal denticles of uniform size and shape covering the dorsal surface.
Habitat and distribution
This species is known to live in the continental shelf at depths of 1–50 m (3 ft 3 in – 164 ft 1 in). Its endemic and common habitat is Hyūga Sea in southern Miyazaki Prefecture, although there have also been several discoveries in Kagoshima and Mie Prefectures.
The Hyuga fanray experiences a decline in population because it is often taken as bycatch with gillnets or trawls, and probably is used for human consumption. It is predicted that the ray has undergone a population depletion of up to 49% over the past 21 years.
