摘要

本研究报告了孟加拉湾西北部奥里萨邦海岸的孟加拉网状河豚Chelonodontops bengalensis的首次记录，该记录基于两个标本(226 - 301毫米SL)，分别于2018年和2019年在Paradeep和Bahabalpur收集。提供了bengalensis的详细形态特征，并与以往的记录进行了比较。该物种与同类的区别在于有12条背鳍，10条肛鳍，18 - 19条胸鳍，10 - 11条尾鳍，鼻器官杯状，大小不等的皮瓣，身体背部覆盖着各种形状和大小的白色斑点，腹部为银白色。我们的研究表明，C. bengalensis的分布范围在孟加拉湾北部从其已知的地理范围孟加拉国和西孟加拉邦向南扩展。

First record of Bengal reticulated puffer Chelonodontops bengalensis (Tetraodontiformes: Tetraodontidae) from Odisha coast, north-western Bay of Bengal with taxonomic notes

The present study reports the first record of Bengal reticulated puffer, Chelonodontops bengalensis from Odisha coast in the north-western Bay of Bengal based on two specimens (226 – 301 mm SL), each collected from Paradeep and Bahabalpur in 2018 and 2019, respectively. The detailed morphological features of C. bengalensis are provided and compared with its previous records. The species is distinguished from its congeners by having 12 dorsal fin rays, 10 anal fin rays, 18 – 19 pectoral fin rays, 10 – 11 caudal fin rays, nasal organ cup shaped with unequal sized flaps, and dorsal profile of body covered with white spots of various shape and size and ventral side silvery white. Our study indicated the range extension of C. bengalensis from its known geographical range i.e. Bangladesh and West Bengal towards south in the northern Bay of Bengal.
