Freshwater Crabs (Potamonids) in the Collection of the Southern Regional Station, Zoological Survey of India, Chennai

The Freshwater Decapod Brachyuran faunal resources are yet to be properly assessed for enumeration and inventorisation despite the availability of classic literature. The baseline information available to the carcinological worker date back to Wood Mason (1871), Rathbun (1904-06) and Alcock (1910), followed by Chopra (1947), Hora (1934), (1935), Dulta (1989) and a series of worker including Deb (1998) and Ghosh and Ghatak (1999, 2000). The Infraorder Brachyura has colonized a series of habitats from terrestrial, fresh water, brackish water to marine exhibiting a high degree of adaptive tendency morphologically and physiologically.
