Juvenile Western Painted Turtle at Jensen Pond. Note that this youngster is not only in the process of molting (see plates being shed on top and around margins of carapace) but has an injury on the front of its carapace. This injury is likely the result of attack by an otter, raccoon, great blue heron or some other predator (Greg Courtney, 9 July 2025).
