Short Description
A species of Squatina diagnosed by presenting a single (or multiple in juveniles) row of enlarged, conical and morphologically distinct dermal denticles over dorsal longitudinal midline, from midlength of pectoral fin base to origin of first dorsal fin (in some specimens, to origin of caudal fin); vertebral centra: maximum values 136, [19578]

southwestern Atlantic from Rio de Janeiro state, Brazil (approximately 23°S) to northern Argentina [19578];

Ovoviviparous, embryos feed solely on yolk [733]. We observed that S. guggenheim presents only one functional ovary, on left side; its antimere is poorly developed, very reduced, and lacking oocytes [19578]; Bony fishes were the main food followed by crustaceans and molluscs [4959]. Diets of different size classes showed significant differences. Male and female diets were not found to differ significantly (P>0.01). Engraulis anchoita was the most consumed fish [4959].

Size / Weight / Age
129 cm TL (male/unsexed; [19579]); 130 cm TL (female)

demersal; marine; depth range 4 - 360 m [19579], usually 4 - 266 m [4959]

18 to 22 vertical rows in both upper and lower jaws, tooth formula 9-9 to 11-11/9-9 to 11-11 [19578];
