Common names
Hyuga fanray

Short Description
This species is distinguished from its congeners by the following set of characters: a row of thorns (strongly hooked) on mid-dorsum of tail; a pair of thorns on anterior part of scapular region (apparent to touch in smallest specimen; 161 mm TL); thorns on orbital, nape and scapular regions not encircled by light yellow or white pigment; dorsal surface covered with minute dermal denticles of uniform size and shape, no obvious larger dermal denticles (smooth to touch) (Ref. 86259).

Distribution
North Pacific: southern Japan.

Biology
According to local divers in Miyazaki, this species often occurs on very shallow sandy bottoms, at depths as shallow as ca. 1 m, in the summer season off the Nichinan Coast, Miyazaki. It is frequently captured by set net within a depth of ca. 50 m from early spring (March) to autumn (November). It was observed by a local fisherman and a fish merchant (pers.comm.), that this species was not included in almost daily set net catches (depth ca. 8-50 m) from November to March in 2007-2008 in northern Miyazaki (Kadokawa Bay) and southern Miyazaki (Meitsu, Nichinan Coast) which indicate that the species avoids lower sea temperatures in the winter season (Ref. 86259).
