生物學特性     字彙 (例如 epibenthic)

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).

底棲魚類捕食無脊椎動物與硬骨魚。 卵生的。 明顯的成對出現。 幼魚可能傾向跟隨大的個體, 例如他們的母親.(參考文獻 205) 卵為長方形鞘囊具有僵硬的觸角沈積在沙灘或泥灘的角落.(參考文獻 205) 卵鞘是 4.8-6.6 公分長與 2.9-3.7 公分寬的.(參考文獻 41249,41253,41298) 被 H. Ishihara 給的深度範圍 (pers.comm。 07/07).

Life cycle and mating behavior Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚

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).西北太平洋: 日本，韓國與台灣.(參考文獻 8630) 似乎限制了小孩 eh 大陸棚日本外與在中國海南至大約廈門.(參考文獻 47737)
