Parasesarma erythrodactyla
<under construction>
Parasesarma erythrodactyla - 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.
Sesarmid crabs are generally considered to be a monophyletic taxon (that is, all genetically deriving from a common ancestor) of Grapsoidea.
Recent reclassifications of the genera Sesarma and Parasesarma (both considered ployphyletic) have resulted in a reshuffling of the speciesCite error: A <ref> tag is missing the closing </ref> (see the help page)..
Distribution of P. erythrodactyla occurs mainly in tropical and subtropical regions along eastern Australia, Indonesia, Taiwan, Korea and India, also may occur along Southern Australia (to be verified).
P. erythrodactyla relies on mangrove leaf detritus for about 80% of its nutrition<ref>{{citenews | author = Connolly, R.M. and Oakes, J.M. | 2007, | title = 'Carbon pathways in estuarine foodwebs: stable isotope evidence further enriched',| publisher = AMSA Conference Abstract Oral Proceedings,| p.26.<ref>, and on benthic microalgae such as diatoms for between 20-35% of its nutrition<ref>{{citenews | author = Oakes, J.M., Connolly, R.M. and Revill, A.T. | 2006, | title = 'Enriched carbon isotope labelling to trace the contribution of benthic microalgae to the nutrition of consumers in mangrove forests',| publisher = AMSA Conference Abstract Oral Proceedings,| p.82.<ref>.
