Ponds, streams, slow-flowing parts of rivers and estuaries.
Their each day exercise consists of alternately basking to elevate physique temperatures and foraging. Higher physique temperatures facilitate digestion. The dwelling vary could also be intensive and include aquatic habitats that may solely be reached by overland migration. In northern populations the slider turtle hibernates on the backside of the aquatic habitat beneath sheets of ice. Adults and juveniles are sometimes frozen to loss of life when drawdowns or excessive temperatures trigger the pond to freeze strong.
FEEDING ECOLOGY AND DIET
Omnivorous, feeding upon aquatic vegetation, bugs, tadpoles, small fish, and carrion.
