The composition and ichthyofaunal diversity of the Bay of Bengal and its adjacent coast have been being explored with time. Australian sawcheek scorpionfish, Brachypterois curvispina is a newly reported species in Bangladeshi water recorded from the St. Martin Island (coral reef) off the Bay of Bengal coast. The identity of this species was confirmed by comparing it with the published morphological description of a specimen reported from the Australian coast. The presence of posteriorly directed lachrymal spines is the key character of this species. Its preferred food items were observed small fish, shrimp, lobster, crab, and some aquatic insects. The dispersal of this species in this geographical area illustrates a considerable expansion of its distributional range, the previously reported Australian coast which is far off from the present record. Although the actual cause of dispersal is unexplored, climate change and global warming are assumed to stretch out the species distribution range. This discovery of Brachypterois curvispina provides a new non-native species record in the coral reef of Bangladesh and represents the northern-most dispersal in the Indo-Pacific region.

随着时间的推移，孟加拉湾及其邻近海岸的组成和鱼类的鱼类多样性得到了探索。澳大利亚锯齿鲈，Brachypterois curvispina是从孟加拉湾海岸附近的圣马丁岛（珊瑚礁）记录的孟加拉国水中的新报道物种。通过与澳大利亚海岸报道的标本的形态描述相比较，证实了该物种的身份。后向泪腺棘的存在是该物种的关键特征。它的首选食物是小鱼，虾，龙虾，螃蟹和一些水生昆虫。该物种在该地理区域的散布说明其分布范围有相当大的扩展，以前报道的澳大利亚海岸距离目前的记录还很远。尽管尚无真正的扩散原因，但假定气候变化和全球变暖扩大了物种分布范围。这个发现Brachypterois curvispina在孟加拉国的珊瑚礁中提供了一个新的非本地物种记录，代表了印度太平洋地区最北端的扩散。
