Megachasmidae (megamouth sharks)

Megachasma pelagios (megamouth shark) ( fig. 35)

The six specimens included in the analysis came from California, Indonesia, Japan, and Taiwan, and thus represent essentially only the Pacific elements of the distribution of this species. The range in pairwise differences among these specimens was 0–10, with an average of pairwise differences of 3.5.

Odontaspididae (sand tiger sharks): Group 2

Odontaspis ferox (smalltooth sand tiger) ( fig. 35)

Both of the included specimens of this species were collected from the Azores and thus represent only a very small portion of the distribution of this species. Nonetheless, these specimens were identical in sequence.

Odontaspis noronhai (bigeye sand tiger) ( fig. 35)

Only a single specimen of this species, collected from Brazil, was included in the analysis. The average of the pairwise differences between the specimens of this species, and those of Odontaspis ferox was 93.
