Kort beskrivning
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 22 - 29. Body moderately deep; belly with 15 to 18 + 9 to 12 scutes. Mouth small. Last dorsal fin ray long, but less the distance from snout tip to pelvic fin base; anal fin relatively short. Scales somewhat small, somewhat irregular. A dark spot behind gill opening. Distinguished from Opisthonema species by its anal fin which is longer than head and well behind dorsal fin base.
Body shape (shape guide): fusiform / normal; Cross section: compressed.
Occurs in rivers and perhaps in lakes. A filter-feeder, its feeding and breeding habits presumably similar to other Dorosoma species. More data needed.
