ECHINORHINIDAE (PRICKLY SHARKS)

Five specimens initially identified as Echinorhinus brucus formed a single cluster ( Fig. 2). When com- pared with Echinorhinus brucus and Echinorhinus cookei specimens (the only recognized species in this family) reported by Naylor et al. (2012), the five Oman specimens formed a separate cluster ( Fig. 6). Given their distinct separation, genetic distances were calculated between the Oman specimens and the Echinorhinus spp. reported by Naylor et al. (2012). The mean distance between the current specimens and E. brucus was 5.04 ± 0.70% while it was 5.23 ± 0.76% between the current specimens and E. cookei . By comparison, the mean distance between E. brucus and E. cookei was 6.07 ± 0.81%. Consequently, the Oman specimens have been labelled Echinorhinus sp.
