Ecology & Habitat

Habitat

Habitat includes marshes, swampy weedy lake margins, wetlands along the edges of large rivers, oxbow lakes, beaver ponds, slow mud-bottomed streams, shallow sloughs with rotting logs, floodplains, drainage ditches, and brackish tidal areas (Dundee and Rossman 1989, Werler and Dixon 2000, Ernst and Ernst 2003, Trauth et al. 2004). This fossorial, semiaquatic snake burrows in soft soil and among wet debris and mats of vegetation along the water's edge. Eggs are laid in earthen cavity, sometimes in alligator nests (Copeia 1993:219-222). In South Carolina, juveniles entered aquatic habitats in spring (mainly) or in fall (Semlitsch et al. 1988).

Reproduction

Lays clutch of 6-104 (usually less than 50) eggs, mostly July-early August. Eggs hatch August-October. Female may stay with eggs until hatching.
