Oxynotidae (roughsharks)

Oxynotus bruniensis (prickly dogfish) ( fig. 45)

A total of 14 specimens of this species were included in the analysis. These were collected from New Zealand and New South Wales in Australia and thus are representative of the temperate Australasian distribution of this species. The analysis yielded one cluster. The range in pairwise differences seen among the 14 specimens was 0–6, with an average of 1.6.

Oxynotus paradoxus (sailfin roughshark) ( fig. 45)

The four specimens of this species included in the analysis were all collected from the eastern North Atlantic, including off Scotland, and were all identical in sequence. These specimens represent the northern elements of this species, which is distributed southward to Senegal. The average of the pairwise differences between this species, and O. bruniensis was 55.3. It is of note that both of these oxynotid species grouped within the cluster containing the somniosids.
