Description 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
