Intersexual hound sharks, Iago cf. omanensis (Triakidae) were found in unusually large numbers from India coast, north-western Bay of Bengal. A total of 154 specimens were collected during August 2018 to July 2019 from Digha Mohana Fish Landing Centre (West Bengal, India) whose size ranged from 21.5 to 59.7 cm total length (TL) with a mean length of 40.06 ± 0.57 cm (Mean ± SE, n = 154). Out of these 154 samples, most of the specimens (94.77%, n = 145) exhibited uncalcified claspers, except a few which were having long, calcified claspers (5.22%, n = 8). Most of the sharks appeared to be male juveniles from external observations, but upon dissection it was noticed that all specimens except one were fully functional females with clearly visible ovaries, oviducal glands, oviducts, uteri and a few with pups. Only one specimen had male primary and secondary reproductive structures. The present study reports instance of hermaphroditism in large numbers in any shark population which is quite rare and unusual and therefore, necessitates a comprehensive and focused study to understand the reproductive strategy of the species.

两性猎犬鲨鱼，Iago参见。阿曼（Triakidae）在印度海岸，孟加拉湾西北部的异常大量发现。在2018年8月至2019年7月期间，从Digha Mohana鱼登陆中心（印度西孟加拉邦）收集了154个标本，其大小范围为全长21.5至59.7厘米，平均长度为40.06±0.57厘米（均值± SE，n ＝ 154）。在这154个样本中，大多数标本（94.77％，n = 145）表现出未钙化的熔解，只有少数具有长而钙化的熔解（5.22％，n = 8）。从外部观察来看，大多数鲨鱼似乎是雄性幼鱼，但在解剖后发现，所有标本均是功能齐全的雌性，具有清晰可见的卵巢，输卵管，输卵管，子宫和少数带有幼崽的雌性。只有一个标本具有男性一级和二级生殖结构。
