摘要：

Mud crab (Scylla serrata) burrows in an estuarine mangrove intertidal zone were identified as potential microhabitats for small fishes. The pool-like habitats, created by these burrows, were sampled for fishes during nocturnal and diurnal low tide events, over the new moon period. A total of 1103 fish, comprising a single gobiid species (Redigobius dewaali), were collected from eight burrow-pools. The utilisation of these burrow-pools by large numbers of a single ichthyofaunal species suggests that there is a degree of commensalism between S. serrata and R. dewaali in these intertidal habitats.
