簡短描述
檢索表 | 型態特徵 | 形態測量圖
Mostly found in surf of sand beaches, but reported from trawl catches at depths up to 73 m. Also occur near rocks, pilings and other sources of cover and food. Usually form small groups. Also caught from piers and skiffs. Feed preferably on sand crabs but also eats clams and other invertebrates. Viviparous, female carries the developing young (Ref. 205). Minimum depth range based on ecology (Ref. 96339).
大部份發現於沙灘的海浪了, 但是記錄自拖網捕捉在深度達到 73 公尺。 也生活於靠近表面的岩石,樁材與其他來源與食物。 通常形成小群魚群。 也從碼頭與小艇捕捉。 可能地在沙子螃蟹身上為食也吃蛤與其他的無脊椎動物。
