Actinopteri (ray-finned fishes) > Cypriniformes
(Carps) > Leuciscidae
(Minnows) > Pogonichthyinae
Etymology: Notropis: A misnomer given by Rafinesque to shriveled specimens, with the meaning of "back keel"; from Greek, noton = back (Ref. 45335); maculatus: From the word maculatus, meaning spotted (Ref. 10294).
Environment: milieu / climate zone / depth range / distribution range
Freshwater; benthopelagic. Subtropical; 38°N - 27°N
North America: in Atlantic, Gulf, and Mississippi River basins from Cape Fear River in North Carolina, USA to Sabine River in Texas, USA; north in Former Mississippi Embayment to southern Illinois, USA; throughout Florida, USA except in extreme southern tip.
Size / Weight / Age
Maturity: Lm ?  range ? - ? cm
Max length : 7.6 cm TL male/unsexed; (Ref. 5723); common length : 5.2 cm TL male/unsexed; (Ref. 12193); max. reported age: 1.00 years (Ref. 12193)
Usually occurs near vegetation in swamps, ponds, backwaters, pools of small to large rivers (Ref. 5723, 10294) and oxbow lakes. Feeds on microcrustaceans (chydorid cladocerans, cyclopoid copepods, ostracods), rotifers, unicellular algae (desmids and diatoms), and small dipteran larvae (Ref. 10294).
