Alopias superciliosus (LOWE, 1841)
Description after BASS et al. 1976: [#133]:
TEETH: The teeth from a 363cm mature male A. superciliosus are shown in pl. 12. Those of a young 61cm female are generally slightly broader, possibly a reflection of sexual dimorphism. The teet numbered 12 - 12/11 - 11in the female. Counts of 9 - 10/10 - 10 are given for an eastern pacific specimen (Fitch and Craig 1964) and 11 - 11/10 - 10 for a western Atlantic specimen (Bigelow and Schroeder 1948).
