Etymology: Deuterodon: Greek, deuter = second + Greek, odous = teeth (Ref. 45335); oyakawai: Named for Osvaldo T. Oyakawa from MZUSP, the collector of many of the specimens that served as the basis of this paper, in appreciation of his major contributions to our knowledge of the fishes of the rio Ribeira de Iguape basin.
Eponymy: Dr Osvaldo Takeshi Oyakawa is a marine biologist and limnologist at the Museu de Zoologia da Universidade de São Paulo where his doctorate was awarded (1998). [...] (Ref. 128868), visit book page.

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).
Fish scales were found in the stomach contents of three specimens (Ref. 96884).

Estimates based on models
Phylogenetic diversity index (Ref. 82804): PD50 = 0.6250 [Uniqueness, from 0.5 = low to 2.0 = high].
Bayesian length-weight: a=0.01096 (0.00498 - 0.02415), b=3.09 (2.92 - 3.26), in cm total length, based on LWR estimates for this Genus-body shape (Ref. 93245).
Trophic level (Ref. 69278): 3.1 ±0.4 se; based on size and trophs of closest relatives
Resilience (Ref. 120179): High, minimum population doubling time less than 15 months (Preliminary K or Fecundity.).
Fishing Vulnerability (Ref. 59153): Low vulnerability (10 of 100).
