Parasesarma erythrodactyla, also known as the red-handed shore crab, is a burrowing crab inhabiting mangrove forests in Australia and Southeast Asia. It is immediately identifiable by its bright red chelipeds (claws) and green/brown carapace.
Distribution of P. erythrodactyla occurs mainly in tropical and subtropical regions along eastern Australia, Indonesia, Taiwan, Korea and India . They may also occur along southern Australia (to be verified).
P. erythrodactyla relies mangrove leaf detritus for about 65%-80% of its nutrition,[1] and on benthic microalgae such as diatoms for between 20% and 35% of its nutrition.[2]
Sesarmid crabs are generally considered to be a monophyletic taxon (that is, all genetically deriving from a common ancestor) of Grapsoidea, but recent reclassifications of the genera Sesarma and Parasesarma (both considered polyphyletic) have resulted in a reshuffling of the species.[3]
A type specimen exists in the Melbourne Museum Discovery Centre (object drawer 15).[4]
