12-9-2023 BOLOGNA, ITALY - RIVER COOTER TURTLE (Pseudemys concinna)

The river cooter (Pseudemys concinna) is a species of freshwater turtle in the family Emydidae. The species is native to the central and eastern United States, but has been introduced into parts of California, Washington, and British Columbia.

The river cooter basks on logs or sun-warmed rocks, and is frequently found in the company of other aquatic basking turtles (sliders and painteds) sometimes piled up on top of each other. All are quick to slip into the water if disturbed. Diurnal by nature, P. concinna wakes with the warming sun to bask and forage. It can move with surprising speed in the water and on land. It is not unusual for it to wander from one body of fresh water to another, but many individuals seem to develop fairly large home ranges, which they seldom or never leave. It sleeps in the water, hidden under vegetation. In areas that are quite warm it remains active all winter, but in cooler climates can become dormant during the winter for up to two months, in the mud, underwater. It doesn't breathe during this time of low metabolism, but can utilize oxygen from the water, which it takes in through the cloaca. The river cooter prefers to be well hidden under aquatic plants during the winter dormancy period or while sleeping each night.
