There are a few different species of turtles that can have yellow markings on their shells. Here are some of the most common varieties:
Eastern Box Turtle
The eastern box turtle is one of the most widespread turtle species in North America. They are characterized by their highly domed, hinged plastron (bottom shell) that allows them to completely enclose themselves within their shell. Eastern box turtles typically have an olive to brown base color with orange, yellow, or red patterned markings on their carapace (top shell). The yellow patterns tend to be radiating lines or patches rather than solid blocks of color.
Ornate Box Turtle
Closely related to the eastern box turtle, ornate box turtles have more pronounced yellow markings on their carapace. Their shells often have a base color of olive green with interconnected yellow lines that form intricate designs. Some individual ornate box turtles may have so much yellow that it becomes the predominant shell color rather than just accents.
Yellow-Blotched Map Turtle
As their name suggests, yellow-blotched map turtles have distinctive yellow blotches on their carapaces. Their base color tends to be olive green, and they have bold yellow spots that are outlined in black. The blotches are concentrated towards the center of the shell rather than the outer edges. Yellow-blotched map turtles are semi-aquatic and found primarily in river systems in the central United States.
Eastern Painted Turtle
Painted turtles are aptly named for their beautifully patterned plastrons and carapaces. The eastern painted turtle is the most widespread painted turtle species. Their olive to black shell has yellow lines along the seams as well as yellow and red markings radiating from the center. The red markings tend to predominate in older eastern painted turtles, while younger ones have more yellow.
Yellow Mud Turtle
As their name implies, yellow mud turtles have yellow as their primary shell coloration. Their carapaces range from bright yellow to dull mustard yellow. Some individuals may have darker smudging or markings, but overall yellow is the predominant color. Yellow mud turtles are small, semi-aquatic turtles found in the central United States.
Razor-backed Musk Turtle
While musk turtles usually have dark brown or black shells, some populations of razor-backed musk turtles have yellow plastrons. Rather than spots or patterns, their yellow coloring consists of solid blocks on the plastron segments. The carapace remains a dark brown or black. Razor-backed musk turtles get their name from the prominent keel that runs down the center of their carapace.
Spiny Softshell Turtle
Some female spiny softshell turtles may take on a temporary yellow coloration during the breeding season. Typically these aquatic turtles are gray or brown with a leathery, pancake-shaped shell. But when ready to mate, the throat and edges of the carapace can turn yellow-orange. This color change recedes when the breeding season is over. It likely helps attract males for mating.
Conclusion
In summary, there are a number of North American turtle species that can have yellow markings on their shells. This includes some prominent species like the eastern box turtle and eastern painted turtle. The yellow patterns take different forms, including solid blocks, radiating lines, and blotches. The vibrant coloration serves various functions, from camouflage to mating displays. It adds to the incredible diversity and beauty of the turtle world.
