利用40 ~ 20 000 Hz的声波记录和扫描电镜技术，对采自新加坡Mandai红树林的两种芝麻蟹Perisesarma eumolpe（De Man）和P. indiarum（Tweedie）的声信号和发声结构进行了研究。声音感受器，巴特的myochordotonic器官，被确定在这两个物种。只有雄性螃蟹被发现显示声学，只有在激动的相互作用。本研究还揭示了关键的物种特异性的差异，在形态学的摩擦器官，摩擦运动和产生的声音。研究结果表明，声音信号可能是一个重要组成部分，在社会行为的红树林芝麻蟹。
Acoustic signalling and sound production structures in the sesarmid crabs Perisesarma eumolpe (De Man) and P. indiarum (Tweedie) from Mandai mangroves, Singapore, were examined using 40 to 20 000 Hz sound recordings and scanning electron microscopy. The sound receptor, Barth's myochordotonal organ, was identified in both species. Only male crabs were found to display acoustically, and only during agonistic interactions. The present study also revealed key species- specific differences in the morphology of the stridulatory organs, stridulatory movements and result- ing sounds produced. The findings show that acoustic signalling may be a significant component in the social behaviour of mangrove sesarmid crabs.
