Ecology: Commonly found in slow moving streams, creeks, drainage ditches, and ponds with abundant vegetation and bottom layer of organic matter (Scott and Crossman 1973). Primarily consumes benthic invertebrates (ostracods, cladocerans, copepods, chironomids, gastropods) and occasionally small fishes (Peckham and Dineen 1957).
Means of Introduction: Released lab animals in Massachusetts. First collected in 1975 in Massachusetts (Hartel et al. 2002). Unknown in Maine, Montana, Oklahoma, and Texas. Biologists of the Oklahoma Department of Wildlife Conservation found a single specimen in a shipment of fathead minnows from a fish farm in Pontotoc County, Oklahoma (Pigg et al. 1996).
Status: Established in Connecticut, Massachusetts, and Maine. Reported in Montana, Oklahoma, and Texas.
