Mar. Evol. Terrestrial adaptations on the Anomura (Decapoda, Branchyura). Female crabs possessed more species of parasites and symbionts, and had a more specialized fauna than did male crabs. This study evaluates the effects of different water temperatures on the fatty acid (FA) composition and histological development of the gills in the blue swimmer crab, Portunus pelagicus. The results of the histological gill analysis showed that the number of hemocytes in the anterior gills of the crabs increased proportionately with the increases in temperature. (2013). & Jones, M.B.

The purpose of this study is to identify the biology of the blue swimming crab in the Banyuasin Estuary. Biol., 77(7): 785-803. Three levels of water temperature (24 °C, 28 °C, and 32 °C) were used to determine their effects on the first 119 days of the crabs’ development after C8 stage in a recirculating aquaculture system. It is yet unclear whether sub-lethal ammonia-N levels cause irreparable damage to aquatic crustaceans, or if recovery is possible, the potential factors involved.

The parasites of some decapod crustaceans are known to cause sterilisation of their hosts, and can thus have an important impact on the population dynamics of infested species. Portunus sanguinolentus (Herbst, 1783) inhabit the same area but it is easily distingushed by their 3 prominent maroon to red spots on posterior 1/3 of carapace.

Portunus armatus (formerly Portunus pelagicus), also known as the flower crab, blue crab, blue swimmer crab, blue manna crab or sand crab, rajungan in Indonesian, and alimasag in Tagalog, is a large crab found in the intertidal estuaries around most of Australia and east to New Caledonia. Various aspects of the biology of the blue manna crab Portunus pelagicus have been investigated in the large Peel-Harvey estuarine system of Western Australia, using samples collected regularly by beach seine, gill net and otter trawl between February 1980 and July 1981. ; Ng, N.K.
