生物學特性     字彙 (例如 epibenthic)

Generally found offshore, but may also encountered in coastal areas (Ref. 9279). Oviparous (Ref. 205). Eggs may be found attached to objects in the water by tendrils on the egg's surface (Ref. 205). Usually caught with the help of artificial lights (Ref. 9279). Marketed fresh and salted (Ref. 9279). The flesh is of good quality (Ref. 9279).

通常發現於外海了, 也但是可能在沿岸區域見到.(參考文獻 9279) 卵生的.(參考文獻 205) 卵可能被發現於在卵的表面上的捲鬚水依附於目標。 (參考文獻 205) 通常用人造光的幫忙捕獲了。 (參考文獻 9279) 在市場上銷售生鮮地了與鹽醃的.(參考文獻 9279) 肉是有好品質的。 (參考文獻 9279)
