Hexanchus griseus (Bonnaterre)

(Figs. 5B, 17 E–H)

All three specimens (SL-91, SL-105, and SL-106) of Hexanchus griseus examined were seen at the landing site of the deep-sea longline fishery in Mutur in the Eastern Province. The upper and lower jaws of SL-91 have been deposited in the BRT Ichthyology Collection (BRT-I 0023). These specimens are morphologically consistent with H. griseus . All three specimens formed a tight cluster with our reference specimen of H. griseus (JQ518727) from the Caribbean Sea in the tree resulting from the Neighbor-Joining analysis. They were identical in sequence to each other and differed from the reference specimen by 2 bp.

This is the name currently applied to this species in Sri Lanka (e.g., De Silva 2006, 2015; Morón et al. 1998; Joseph 1999).
