Squaliolus sp.

Both recent species, S. aliae Teng, 1959 and S. laticaudus Smith and Radcliffe, 1912 , feed on squids and bony fishes (Ebert et al., 2021); the former has a TL of 4.4 ±0.57 and the latter, 4.2 ±0.73 (Froese and Pauly, 2019). S. aliae lives from 0 to 2000 m deep and S. laticaudus from 10 to 750 m (Ebert et al., 2021).

ORDER PRISTIOPHORIFORMES Berg, 1958

Family Pristiophoridae Bleeker, 1859

Genus Pristiophorus Müller and Henle, 1837

Pristiophorus suevicus Jaekel, 1890

Tooth type: Clutching.

There are seven recent species within this genus, some of which with unknown biology (Ebert et al., 2021). Those whose biology is known feed on small fishes and crustaceans (Ebert et al., 2021). The members of this genus can be subdivided into two groups by habitat (Ebert and Wilms, 2013): one of temperate waters and mostly coastal and continental shelf species, and another of tropical, deep-waters, continental and insular slope species, living near the bottom (maximum known depth of 630 m; Compagno et al., 2005). TL values for the seven recent species range from 3.8 to 4.2 (Froese and Pauly, 2019).
