註釋

The phenomena of herbivory (i.e. the direct exploitation of living plant material) and tree-climbing by crabs, of which few accounts seem to exist for the Indo-Pacific, is reported for the first time from mangrove forests in Singapore. A review of tree-climbing crabs notes that previous reports seem to include only New World species. In this study, the tree-climbing crabs can be devided into two categories. The first consists of non-burrowing habitual climbers: Selatium brockii, seen up to 4 metres high on tree trunks, may be considered arboreal but Metopograpsus spp., not seen above 3 metres, can be found both on the ground as well as on tree-trunks. The second group consist of burrowing crabs of the genus Episesarma which are facultative climbers during periods of nocturnal low tide. E. versicolor, E. chengtongense and E. singaporense, commonly found on the mangrove floor, can climb to heights above 5 metres.
