Family Hemiscylliidae

Bamboo sharks are poorly studied in the Bangladesh region, though a total of five species have been recorded; Chiloscyllium burmensis , C. griseum , C. indicum and C. punctatum ( Hoq et al. 2011; Haque et al. 2019a) and most recently C. hasseltii ( Datta et al. 2020) . In this study, a total of 129 specimens of Chiloscyllium hasseltii ( Figure 16 ) were morphologically identified. Eleven specimens that appeared morphologically consistent with Chiloscyllium arabicum ( Figure 17 ) were also recorded, but in the absence of genetic data this warrants further investigation.
