What is turtles purple?

There are no turtle species that are specifically categorized as "purple turtles." However, there are some turtle species that have purple or violet hues on their skin, such as the purple sea turtle (Chelonia mydas agassizii) which is a subspecies of the green sea turtle. The purple sea turtle has a unique coloration on its skin due to a genetic mutation that causes it to produce red and yellow pigments instead of the usual greens. This gives it a purple hue that can vary in intensity.

Other turtle species, such as the Eastern box turtle (Terrapene carolina carolina), also have hints of purple in their skin. The shell of the Eastern box turtle can range from brown to black, and may have splashes of yellow, orange, or purple on the edges or domed parts of the shell.

It's important to note that not all purple coloration in turtles is natural. Some pet turtles may be dyed or painted with non-toxic pigments to create a colorful appearance. This practice is not recommended and can cause stress, health issues, and harm to the turtle's natural coloration.
