The reproductive biology of commercially important Alopias superciliosus and Alopias pelagicus bears great importance. The present study reports the gravid females from the Andaman Sea for the first time. Parturient sharks have been rarely observed in the wild, with very sparse data regarding the reproductive strategies of most oceanic species from Andaman and Nicobar waters. During this study, from the uterine cavity of Alopias superciliosus and Alopias pelagicus, two pups each were recovered alive. Total Length (TL) of gravid Alopias superciliosus and Alopias pelagicus measured to be 353 cm and 286 cm, weighing 145 kg and 65 kg respectively. Both the gravid sharks bore male and female embryos in right and left uterus. The embryos found in Alopias superciliosus measured 140 cm (male) and 143 cm (female) in TL, whereas the embryos found in Alopias pelagicus measured 120 cm (male) and 122 cm (female). The present study estimated the gestation period for 9 months in Alopias pelagicus as well as in Alopias superciliosus. Though further investigation are required to confirm various reproductive informations such as delayed or late maturity, synchronous reproductive cycle and low biological productivity however this study confirms only two embryos per uterus.Keywords: Gravid; Litter; Embryos; Viviparous; Oophagus; Alopias superciliosus; Alopias pelagicusCitation: Das P, Sinha MK, Bhargava AK, Singh P, Sahu KC, et al.
