Short description
Bestämningsnycklar | Morfologi | Morfometri
Taggstrålar i ryggfenan (totalt) : 0; Taggstrålar i analfenan: 0; Mjukstrålar i analfenan: 24 - 30. Body moderately deep; belly with 15 to 18 + 9 to 12 scutes. Mouth relatively large; lower jaw comparatively long, upper jaw reaching to vertical from eye center. Last dorsal fin ray long, but less than distance from snout tip to pelvic fin base; anal fin moderately long. Scales small, somewhat irregular. A dark spot behind gill opening. Gill rakers fine and numerous.
Occurs in rivers and lakes. A filter-feeder, its feeding and breeding habits presumably similar to other Dorosoma species. More data needed.
