Descrição breve
Morfologia | Morfometria
Raios dorsais moles (total): 11; Vértebras: 33 - 36. Probolodus sazimai is distinguished from its two congeners, P. heterostomus, P. oyakawai, by the following characters: six transverse series of scales from insertion of pelvic fin to lateral line (vs. seven/eight); 12 scales along middorsal line between posterior termination of base of dorsal fin and adipose fin (vs. 14-17 and 13-16, respectively); two pairs of uroneurals (vs. absent or just one pair); anterior margin of the hypurals 2 and 3 in contact, not fused (vs. hypurals 2 and 3 distinctly separate); end piece or stay of the dorsal fin leaning against or fused in the last pterygiophore (vs. somewhat removed of the last pterygiophore); fourth basibranchial completely cartilaginous (vs. ossified); dorsal margin of the opercle more elevated than the hyomandibular (vs. opercle and hyomandibular practically aligned); anteromedially projection of the mesethmoid wide, separating completely the premaxillary (vs. short projection, not separating completely the premaxillary). It can be further differentiated from P. heterostomus by having 36-43 perforated scales on the lateral line (vs. 45-56 perforated scales) (Ref. 96884) (Ref. 96884).
Fish scales were found in the stomach contents and between gill rakers of one specimen while leaf fragments, insects and scales were encountered in the oral cavity of three specimens (Ref. 96884).

Nível Trófico (Ref.
69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resiliência (Ref.
