In the Laguna Segara Anakan, there are two species of mangrove crab such as: Scylla serrate and Scylla transquebarica. Both of these species are always in the same water conditions in the Segara Anakan Lagoon, Cilacap. The purpose of this study was to examine the co-existence both species populations (S. serrate and S. transquebarica) in the Segara Anakan Lagoon. Sampling were carried out on April and June 2019 in three locations namely Klaces, Panikel and Sapuregel. Traps were used to collect crab samples. According to the research result that in the Klaces, the number of S. serrata (n=17) is greater than the number of S. transquebarica (n=4). Whereas in Panikel and Sapuregel, the number of S. transquebarica was more than the number of S. serrata. The presence of S. serrata and S. transquebarica in mangrove habitat is always side by side.

在 Laguna Segara Anakan，有两种红树林蟹，例如：Scylla serrate 和 Scylla transquebarica。这两个物种在 Cilacap 的 Segara Anakan 泻湖中始终处于相同的水环境中。本研究的目的是检查Segara Anakan 泻湖中两种物种种群（ S. serrate 和 S. transquebarica ）的共存情况。采样于 2019 年 4 月和 6 月在三个地点进行，即 Klaces、Panikel 和 Sapuregel。陷阱被用来收集螃蟹样本。根据研究结果，在Klaces，S. serrata（n=17）的数量大于S. transquebarica（n=4）的数量。而在 Panikel 和 Sapuregel，S. transquebarica的数量多于S. serrata的数量。S. serrata和S. transquebarica在红树林栖息地的存在总是并排存在。
