A benthic species found inshore of the continental shelf in muddy, silty and sandy bottoms, usually with seagrass; intertidal to 50 m depth (Ref. 75154). Large numbers of individuals are known to congregate in the shallows of estuaries. The species is capable of burying itself in the sediment and change colors to match the background.
许多的个体被知道在河口的浅滩中聚集。 此鱼种能够在沉淀物中把自己埋藏起来而且改变颜色与背景相配。
Life cycle and mating behavior
成熟度 | 繁殖 | 产卵场 | 卵 | 孕卵数 | 仔鱼
Spawning occurs as male & female swim from vent to vent, about 1 meter off the bottom, while they release eggs & sperms. The pair separates and each swims away as the eggs begin a pelagic phase. 東印度洋: 澳洲南部與塔斯梅尼亞的溫帶水域的特有種。
