Ecology: Trachemys stejnegeri is omnivorous in capitivity; it feeds upon items such as snails, shrimp, and green leaves (Schwartz and Henderson, 1991). Its habitat includes freshwater bodies with soft bottoms and aquatic vegetation especially ponds, swamps, streams and rivers. Nesting occurs April to July yielding 3 to 14 white eggs per clutch (Ernst and Barbour, 1989). It is also known to bask on masses of aquatic vegetation or in dead bushes (Schwartz and Henderson, 1991).
Means of Introduction: "Reptile fanciers" released the specimens into the canal (King and Krakauer, 1966).
Status: King and Krakauer (1966) reported that the species had not been detected since its release.
Impact of Introduction: The impacts of this species are currently unknown, as no studies have been done to determine how it has affected ecosystems in the invaded range. The absence of data does not equate to lack of effects. It does, however, mean that research is required to evaluate effects before conclusions can be made.
