Macrobrachium
Macrobrachium is a genus of freshwater prawns or shrimps characterised by the extreme enlargement of the second pair of pereiopods, at least in the male. The genus is cosmopolitan, found throughout the tropical, freshwater and estuarine ecosystems of both the Old and New Worlds.
The genus has a difficult taxonomic history due to morphological conservation between its species (plesiomorphy), and conversely, variations within a single species (polymorphism), leading to the discovery of cryptic species which were only revealed through genetic analysis and morphometry. This polymorphism may be especially apparent among males, where it is termed heterogeneous individual growth (HIG); in males, this determines the size and morphology that they may grow into, as well as their physiology and behavior.
