本文对马来西亚半岛西南海岸的一种蟹类（学名：Dotilla myctiroides）进行了研究。一年中，从高水位到低水位的样带的平均数量和生物量分别为37.5至579只螃蟹m-2和2.22至50.79 g m-2（湿重）。在一年中的所有月份都发现了结果实的雌性，但在11月至2月和5月至7月这两个活动高峰是明显的。有人认为，这可能与季风对海流的影响有关的食物丰富度的变化。实验室生长研究表明，雄性最长寿命约为13个月（从第一个螃蟹阶段开始），雌性约为10个月。生长速率随蟹体大小的增加而降低。产卵量随雌虫体型增大而增加。
The ocypodid crab,Dotilla myctiroides, was studied on the south-west coast of peninsular Malaysia. The mean numbers and biomass over a year along a transect from high to low water ranged from 37·5 to 579 crabs m−2and from 2·22 to 50·79 g m−2(wet weight) respectively. Berried females were found in all months of the year but two peaks of activity were apparent, from November to February and May to July. It is suggested that this may be related to changes in food abundance associated with the effects of monsoon winds on sea currents. Laboratory growth studies indicated that maximum life span was approximately 13 months (from first crab stage) for males and 10 months for females. Growth rate decreased with increasing size of crab. Egg number increased with size of female.
