ABSTRACT The freshwater crab Barytelphusa cunicularis (Westwood, 1836) is commonly occurring freshwater crab in the state of Maharashtra. It is commonly found in rivers, ponds, lakes, wells, dams, etc. The B. cunicularis is an edible highly nutritious commercially important crab and sold in large numbers in weekly markets in cities, towns and villages in Maharashtra. The brain of crab has been reported to control many physiological activities in crustaceans. The brain and central nervous system (CNS) of crustaceans has been extensively investigated by neuroanatomists. The present research paper gives an account of histological organization of the brain in freshwater crab B. cunicularis. The routine histological techniques with Mallory’ triple staining were used to study histology of the brain. The analysis of results obtained shows that the brain of B. cunicularis consists of a sheath, a number of neuropils, groups of neurosecretory cells and glial cells. The brain is divisible into Pro-, Deuto- and Tritocerebrum. Some giant nerve cells have also been observed. The stained sections of brain showed presence of various types of neurosecretory cells (NSCs). The main types of NSCs observed were type A, B, and C cells.
