Lives in burrows excavated in clean sand, often in association with the sandprawn Callianassa kraussi (Ref. 52193). Restricted to sandy, quiet water areas and is unable to form burrows where the substrate is disturbed by water movements, is muddy or consists of sand with a particle diameter > 0.5 mm (Ref. 28077). Food consists of slow moving benthic organisms like chironomid larvae, gastropods, bivalves and amphipods (Ref. 28077). Breeds throughout summer, males are territorial (Ref. 52193). On exposed shores, they occur deeper than 3.5 m (Ref. 28077, 2798). Occasionally intertidal.
局限于了沙的, 静止的水域区域而且不能够形成洞穴在哪里藉着水运动，底部是扰乱的, 是泥泞的或者由沙子具有一个粒子直径 >0.5 mm 组成。 它的食物由像宝刀鱼仔鱼，腹足动物，二枚贝与片脚类动物的缓慢移动的底栖性生物组成。 在裸露的海岸上，它出现深度超过 3.5 公尺。 (参考文献 28077,2798) 偶然潮间带。
