🔬 Taxonomy

🐟 Physical Description

Dorsal soft rays (total): 11; Vertebrae: 33 - 34. Probolodus oyakawai is distinguished from its two congeners, P. heterostomus and P. sazimai, by the following characters: the base of the large epural not leaning against the urostyle bone (vs. the base of the large epural in contact, not fused the urostyle); first and second infraorbitals contacting but not overlapping (vs. relationship with overlapping or leaning against); posterior portion of the maxilla extended in relation to median portion (vs. posterior portion of the same width than median portion); anterior extension of nasal reaching the lateral projection of mesethmoid (vs. outpacing the end of the projection of mesethmoid). It further differs from P. heterostomus by having 41-43 perforated scales on the lateral line (vs. 45-56 perforated scales), 14-16 scale series around the caudal peduncle (vs. 18-21 scale series around the caudal peduncle), and body relatively shorter, with 33-34 total vertebrae (vs. 34-35 vertebrae) (Re. 96884). : fusiform / normal.
