Habitat and Ecology [top]

Habitat and Ecology: There are various habitats in wooded regions, it can be found in the vicinity of cool clear streams and ponds in the north and in warm, turbid swamps in parts of the south. It disperses from the water's edge into fields and woods in some regions. When inactive, it hides at the bottom of water bodies or in caves in some areas. Eggs and larvae develop in standing water of woodland ponds, bog ponds, stream pools, sloughs and flooded ditches, often in sites with few or no fishes (e.g. Holomuzki 1995).
Systems: Terrestrial; Freshwater
