Western pond turtles are omnivorous and most of their animal diet includes insects, crayfish and other aquatic invertebrates. Fish, tadpoles, and frogs are eaten occasionally, and carrion is eaten when available. Plant foods include filamentous algae, lily pads, tule and cattail roots.
Because of their hard shell, Western pond turtles are generally well protected. However, several predators do threaten this species, especially hatchlings, due to their small size and soft shell. Raccoons, otters, ospreys and coyotes are the biggest natural threat to these turtles, and hatchlings have the additional threats of weasels, bullfrogs, and large fish.
