Painted Turtle by David Marvin
World Turtle Day was created by American Tortoise Rescue as an annual day of recognition to raise awareness about turtles & help preserve endangered turtles worldwide. Michigan has ten species of native turtles including Michigan’s state reptile, the Painted Turtle, but I was today years old when I learned there’s such a thing as the Midland Painted Turtle (pictured above)! Herpman explains in the Painted Turtle entry in his Michigan Herpetological Atlas that:
Four distinct subspecies are recognized, two of which are found in the Great Lakes basin. The Midland Painted Turtle (C. picta marginata) tends to have prominent red stripes on forelegs and neck, and plastron is usually yellow or orangish yellow with elongate dark central blotch that does not cover more than half the plastral width. The Western Painted Turtle (C. picta belli) usually has narrow yellow stripes on forelegs and neck, and a pattern of light lines on the carapace.
Plastron (shell) may be reddish or orangish, with complex central pattern of dark and light lines that extends out along the scute seams and often covers more than half of the plastral width. Intergrade individuals within the overlapping range display a variable blending of these characteristics.
You can see the difference pretty easily in the photos of the Midland Painted Turtle by Kobie Mercury-Clarke on the left and the Western Painted Turtle from the US Fish & Wildlife Service. However, as you can see on the map, Michigan’s Upper Peninsula has some intergrade turtling going on.
David took the top photo last April. Here are some more of his Painted turtle pics along with one of two Map turtles doing a “turtle stack”. See David’s latest pics including a Calico Pennant Dragonfly on Flickr & for sure visit his blog to read about Red Cedar River turtles & other important things.
