Abstract
Abnormal changes in the morphology of the appendages and body segments in decapods crustacean have long been noticed in the wild (Fauvel, 1900), including duplication of structures (Rudolph, 1996; Nakatani et al., 1997), lack of such structures (Kulkarni et al., 1980), reversal of asymmetry (Stevens & Munk, 1991) and deformed sexual appendages (Rodriguez & Campos, 2000). In shrimps, abnormalities of the rostrum have often been reported (De Grave, 1999) and mostly deal with a significant increase in size of the rostrum or in rostral teeth number (Ayub & Ahmed, 1991). Variations in the rostral shape, teeth number or shape and length have been further noticed in several species, e.g., Penaeus penicillatus Alcock, 1905, Penaeus merguiensis De Man, 1888 and Metapenaeus affinis (H.Milne Edwards, 1837) (Ayub & Ahmed, 1991). The present study report the rostral deformity in Parapenaeopsis hardwickii for the first time from Palk Bay
