Alopias pelagicus NAKAMURA, 1935
Description after BASS et al. 1975: [#133]:
TEETH: The distinctive teeth of A. pelagicus are shown in pl. 10. The tooth count in our specimen was 21 - 22/20 - 2 - 20 Apart from the markedly oblique cusps and the denticulations on the outer side, the teeth of A. pelagicus are also relatively small when compared to those of A. vulpinus. The longest tooth from the upper jaws of our A. pelagicus (measured from the tip of the cusp to the end of the root) was 1.6% of total length as compared to 2.6% in a large (376cm) A. vulpinus.
