Scientific Name: Chrysemys picta bellii

The Painted turtles are one of the most widespread turtle species found throughout the United States, including in Colorado. Painted turtles are not an aggressive species and are often kept as pets.

They feed on tadpoles, insects, snails, fish, and various insects. Their native habitat is quiet and shallow waters with a muddy bottom

Painted turtles measure between 5 and 10 inches long. The male of the species is a bit smaller than the female.

Scientific Name: Chelydra serpentina

Snapping turtles are large animals that thrive in slow-moving water with a sandy or muddy bottom. As their name suggests, snapping turtles have powerful jaws that will quickly snap close to catch prey, as well as protect them from predators.

Snapping turtles are not overly aggressive, but they are quick to act if they feel threatened. That is why you should always keep your distance when you see a snapping turtle on land or in the water. 

Snapping turtles feed on various aquatic plants, insects, fish, small mammals, birds,  and amphibians. They have an average lifespan of 10 years, but can live up to 40 years. They spend most of their time in the water, but will go on land during the breeding season.

They measure between 5 and 20 inches long, and feature a leathery shell that is flat and shaped similar to a pancake.

6. Red-eared Slider

Scientific Name: Trachemys scripta elegans

The red-eared slider is considered an invasive species in Colorado and is mostly seen in artificial ponds and lakes, open spaces, and urban parks. It is theorized that this turtle species was brought to Colorado as pets and when they became too large for their owners to care for, they were released in the wild.

Even though this turtle species is native to the southeastern portions of the United States, it can survive the somewhat brutal Colorado winters. Unfortunately, the red-eared slider is problematic since it can impact Colorado’s native turtles, making them compete for basking sites and food sources.
