Brachyuran crabs exhibit varying inhabitation patterns and habitat preferences and their existence and distribution influenced by the environmental factors prevailing in the area. The present study is an attempt to describe the habitat ecology, habitat preference and the distribution of the brachyuran crabs that are listed from the Cochin Backwaters. The study reveals that, rather than the water quality parameters, it is the sediment quality parameters, which influence the distribution of crabs. Apart from the substratum characteristics, salinity and the presence of mangroves also plays a significant role in the distribution of crabs in an area. Distribution of crabs was observed to be highest in the stations with muddy substratum, with high organic carbon content and comparatively high amount of moisture as well as ornamented with luxuriant mangrove patches.

Brachyuran螃蟹表现出不同的栖息地模式和栖息地偏好，并且其生存和分布受到该地区普遍环境因素的影响。本研究试图描述从科钦死水列出的栖息地生态学，栖息地偏好和短臂蟹的分布。研究表明，影响螃蟹分布的是沉积物质量参数，而不是水质参数。除了底层特征外，盐度和红树林的存在在该地区蟹的分布中也起着重要作用。在具有泥质底质的站点中，蟹的分布最高，
