摘要

Nine crocodile sharks, Pseudocarcharias kamoharai (Matsubara, 1936 (Zoological Magazine, 48, 380–382, 1936)), were recently captured as by-catch in hook and line fishery performed in the international waters adjoining the Maldives and landed at Cochin Fisheries harbor (southwestern coast of India). Present records included four males and five females, one of which is considered the largest ever reported gravid female with a total length of 102 cm and weighed 5200 g. Upon dissection, four developing embryos (two male and two female) were observed. All examined embryos were in the intermediate phase measured between 28–30 cm and weighed 70–90 g. The demand for P. kamoharai in Indian Fishery has gone down in the recent decades, however high squalene content in the liver of this fish still attracts buyers from pharmacy companies. P. kamoharai is being listed on the IUCN Red List and considered a “Least Concern (LC)”, and due to the knowledge gap the life history and the distribution of this enigmatic elasmobranch species in the Indian Ocean are not clearly understood. A sustained research initiative needs to be undertaken to understand the distribution and migratory behavior of this species.
