Ecologia
; acqua dolce; salmastro pelagico. Tropical; 10°N - 8°S, 69°W - 47°W (Ref. 188)
South America: lower reaches of the Orinoco, rivers of the Guianas, Amazon at Pará, but undoubtedly elsewhere in its lower part.
Dimensione / Peso / Età
Maturità: Lm ? range ? - ? cm
Max length : 11.0 cm TL maschio/sesso non determinato; (Ref. 105080); common length : 5.0 cm SL maschio/sesso non determinato; (Ref. 188)
Spine dorsali (totale) : 0; Raggi dorsali molli (totale) : 13 - 21; Spine anali: 0; Raggi anali molli: 15 - 18. Belly strongly keeled; two distinct parallel striae on scales; a silver stripe along flank in some specimens. Easily separated from all other clupeids in the area by the sharp retrorse spine on the upper part of the maxilla at about the level of the eye center. Distinguished from the very similar R. bahiensis mainly by having fewer vertebrae (38 or 39) and fewer scales in lateral series (Ref. 188). Body silvery, head yellowish white (Ref. 37032).
Body shape (shape guide): fusiform / normal; Cross section: compressed.
A riverine freshwater species, but also tolerates brackish water. Presumably schooling. Feeds on zooplankton.
