Reproduction in Eastern River Cooters

Eastern river cooters, like many turtles, reach sexual maturity around 6-8 years of age. This significant milestone marks the beginning of their reproductive journey.

Once mature, females lay eggs once or twice a year, depending on environmental conditions such as temperature and food availability. The nesting season typically spans from late spring to early summer.

During the nesting process, the female seeks out a suitable nesting site, often on sandy or muddy banks near bodies of water. She excavate a shallow nest using her hind legs and deposits her eggs inside. These eggs are oval-shaped and may vary in color from white to pale yellow. The clutch size ranges from 3 to 15 eggs, with an average of 7-8 eggs.

After laying her eggs, the female buries the nest to protect them from predators and the elements. The eggs incubate for 60-90 days, depending on temperature. Once the eggs hatch, the baby cooters emerge from the nest and make their way to the water.
