Facultative air-breathing (Ref. 126274); Are residents of intertidal zone with homing behavior (Ref. 32612) found in pools with rocks or boulders. May leave tide pools if aquatic conditions become inhospitable (Ref. 31184). Feed mostly on invertebrates, particularly crustaceans and mollusks. They breathe air when out of water (Ref. 31184) and swim with an eel-like motion (Ref. 9003). Eggs are guarded by the male parent (Ref. 205).
一個定居的潮間帶的種有歸巢的行為 (參考文獻 32612) 發現於水池有岩石或大圓石。 如果水生的環境變成不適居留，可能離開潮池。 (參考文獻 31184) 大部份捕食無脊椎動物, 特別地甲殼動物與軟體動物。 呼吸空氣當離開水面.(參考文獻 31184) 以像鰻魚一樣的運動游泳。
Life cycle and mating behavior
Maturities | 繁殖 | Spawnings | Egg(s) | Fecundities | 仔魚
Nests are constructed beneath boulders where the dense gelatinous cluster of about 10,000 eggs are deposited. The male stands guard and seals the nest from the inside by blocking the entrance with small stones and mud. Eggs hatch after about ten days into planktonic larvae (Ref. 9003).西南太平洋: 紐西蘭的特有種。
