Comments: Type localities of Platessa cornuta and junior synonym Pleuronichthys japonicus from Shimane Prefecture, off Hamada. Known offshore around the Japanese archipelago, southward from southern Hokkaido (along the Sea of Japan to southern East China Sea and Iyo Nada in the Seto Inland Sea. It was recorded from sandy-muddy bottoms at several depth ranges: 40-60 m off Soma, Fukushima Pref.; 25-100 in Kii Channel; ca. 140-150 m off Hamada, Shimane Pref.; 100-150 m off Oda and Hamada (as P. cornutus); ca. 60 m in Seto Inland Sea; 76-143 m in East China Sea; and 30-140 m in the Kii Channel, being especially numerous from deeper than 100. As P. cornutus, it was reported from the coastal waters off Miyagi Pref., Tohoku District, southward along the Pacific coast to Bungo Channel, from Akita Pref., Tohoku District, southward along the Sea of Japan coast through the Tsushima Strait to the East China Sea (Ref. 84246). Not found in northern Hokkaido (Ref. 11230).

Descrição suscinta Chaves de identificação | Morfologia | Morfometria

Raios dorsais (total) : 67 - 81; Raios anais : 48 - 58; Vértebras: 35 - 37. This species is distinguished by the following characters: scale length (from trunk area) is greater than 1.33% of SL, the whole scale outline oval, exposed margin rounded; scales highly deciduous, longitudinal rows occasionally irregular; upper eye area usually greater than that of lower eye, area ratio 0.93–1.44; central longitudinal scales 75-87, scales below lateral line 47-57; abdominal vertebrae 12-13 (mostly 12) (126213).

Inhabits sandy and muddy bottoms in coastal areas (Ref. 9137, 11230); but mainly muddy bottoms in offshore deeper (from ca. 40m) waters, possibly due to its highly deciduous scales, it may avoid sandy bottoms. It occurs in lower densities than P. lighti in shallower coastal waters, including the Seto Inland Sea (Ref. 126213). Recorded from several depth ranges from the following localities: 40-60 m off Soma, Fukushima Prefecture; 40-75 m in Kii Channel; ca. 140-150 m off Hamada, Shimane Prefecture; ca. 60 m in Seto Inland Sea; and, 76-143 m in East China Sea. It was also reported from 30 to 140 m in the Kii Channel, being especially numerous from deeper than 100 m (Ref. 84246). The flesh of this species is soft, and the quality declining quickly after death, that the species has a low market value (Ref. 126213).
