Sand bubbler crab : ウィキペディア英語版 | Sand bubbler crab
Sand bubbler crabs (or sand-bubblers) are crabs of the genera ''Scopimera'' and ''Dotilla'' in the family Dotillidae. They are small crabs that live on sandy beaches in the tropical Indo-Pacific. During the low tide, they form inflated sand pellets that are disintegrated by the incoming high tide. ==Description== Sand bubbler crabs are small crabs, around across the carapace, and they are characterised by the presence of "gas windows" on the merus of the legs; in ''Dotilla'', these windows are also present on the thoracic sternites.〔 A similar system has evolved in parallel in the porcelain crab genus ''Petrolisthes''.
