成熟度: Lm ? range ? - ? cm
Max length : 30.0 cm SL 雄魚/尚未辨別雌雄; (Ref. 559); 最大體重: 1.0 kg (Ref. 56557)
背的軟條 (總數) : 67 - 81; 臀鰭軟條: 48 - 58; 脊椎骨: 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).
Cross section: flattened.
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).
