Creature feature: The common snapping turtle. The common snapping turtle is one of two snapping turtles found in Illinois, but it’s the only one that lives in the northern part of the state. Snapping turtles are named for their snapping bite, but they aren’t generally aggressive, particularly in water. They can be a little feisty on land, however.
A snapping turtle’s shell can be 8 inches to 18 inches long, and they can weigh between 8 pounds and 35 pounds. They spend almost all their time in the water, preferring slow-moving waterways with muddy or sandy bottoms.
Snapping turtles are picky when it comes to food. The eat both plant and animal matter, including aquatic leaves and grasses, algae, fish, frogs, snakes, birds, mammals, insects and even other turtles.
While snapping turtles are not often hunted by other animals, their nests are. Birds, raccoons, skunks and more will raid their nests to eat the eggs. As many as 90% of snapping turtle nests are destroyed by predators every year.
Fun fact: Snapping turtles have existed for about 90 million years — since dinosaurs roamed the earth — and they have changed surprisingly little in that time. They still look and live much the same as they did in the age of dinosaurs.
