生態学
海 底生の; 海洋回遊性 (Ref. 51243); 深さの範囲 20 - 230 m (Ref. 106604). Temperate
Northwest Pacific: Japan, Korea and Taiwan (Ref. 8630). Appears to be confined to the continental shelf off Japan and in the China Seas south to about Xiamen (Ref. 47737).
Length at first maturity / サイズ / 重さ / 年齢
Maturity: Lm ?, range 39 - ? cm
Max length : 57.0 cm TL オス/雌雄の選別がない; (Ref. 111281); 最大公表体重: 815.70 g (Ref. 125279)
Bottom-dweller that feeds on invertebrates and bony fish. Oviparous. Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205). Eggs are oblong capsules with stiff pointed horns at the corners deposited in sandy or muddy flats (Ref. 205). Egg capsules are 4.8-6.6 cm long and 2.9-3.7 cm wide (Ref. 41249, 41253, 41298). Depth range given by H. Ishihara (pers.comm. 07/07).
Life cycle and mating behavior

Oviparous, paired eggs are laid mainly at night (Ref. 44760). Batches of eggs are laid in three to six-day interval on sand bottom. Embryos feed solely on yolk (Ref. 50449). Distinct pairing with embrace. Young may tend to follow large objects, such as their mother (Ref. 205).
