Three-toed box turtle

Terrapene carolina triunguis


The carapace is relatively high and dome-shaped with a low keel running down the midline. The carapace is brown, but may hae an indistinct pattern of yellow to orange lines and spots. An older individual may be patternless and have a pitted shell. The unpatterned plastron is tan to dark brown and has a hinge. In a male, the posterior part of the plastron is slightly concave. Some males have a great deal of red or orange coloration on the head. Normally, this turtle has only three toes on the hind foot, but occasionally it has four toes. The hind feet are rather stumpy and are not webbed. The male usually has red eyes, whereas a female has yellow or brown eyes. (information from "A Field Guide To Amphibians and Reptiles of Oklahoma")




This turtle was spotted in Sequoyah National Wildlife Refuge during a turtle monitoring session. I was helping some grad students do some radio telemetry, which is part of a larger study to track turtle movements and check for possible ranavirus.

Here's an article that explains the virus:
