Etymology: Serrasalmus: Latin, serran, serranus, saw and a fish of genus Serranus + Latin, salmo = salmon (Ref. 45335); odyssei: Name applied to the locally known piranha 'suave' and refers to the taxonomic confusion with this species at the beginning of the fieldwork during the present study.

Short description

Μαλακές ραχιαίες ακτίνες (συνολικά) : 13 - 15; Μαλακές εδρικές ακτίνες: 28 - 33. This species is distinguished from its congener in the Upper Amazon by the following set of characters: short supraoccipital spine 0.13-0.17% of SL (vs. typical range between 0.17-0.22% of SL in Serrasalmus but sometimes reaching 0.15 and 0.16 in S. hollandi and S. altispinnis); shallow body 0.45-0.57% of SL (vs. typical body height 0.50-0.62% in Serrasalmus); short dorsal fin, between 0.18-0.20% of SL and 13-15 branched rays (vs. 0.19-0.24% of SL in Serrasalmus); short anal fin, typical 0.32-0.37% of SL with 28-33 branched rays, but overlapping sometimes with other Serrasalmus); adipose fin located on the very posterior part of the body and distant from the dorsal fin end, typically R15 ranging between 0.19-0.22% of SL, but overlapping with other Serrasalmus with R15 ranging between 0.17-0.21% of SL); low number of scales between the lateral line and the dorsal fin, 23.5-29.5 (vs. 28.5-36.5 in other Serrasalmus); an intermediate number of prepelvic serrae 20-24 (Ref. 85594).
This species is reported from the clear- to black-water rivers of the Upper Madeira where it seems to be scarce in white waters. Inhabits the shallow part of the river near the shores especially where dead woods accumulate and scarce in the running part of rivers. Apparently common in syntopy with young S. rhombeus individuals of equal size (Ref. 85594).
