Yellow-blotched Map Turtle
A high-spined turtle with yellow shell blotches lives only in Mississippi’s Pascagoula River system, where intact current and woody snags are essential.

Yellow-blotched map turtles are confined to the Pascagoula River system, one of the largest relatively free-flowing river networks in the lower United States. Their keeled shells carry yellow blotches, and strong sexual size differences reflect different diets and feeding structures between females and males.
Water-quality decline, channel change, snag removal, illegal collection, road mortality, and repeated basking disturbance threaten the species. A quiet distant view is more informative than a close approach: watch how individuals choose sun, current, and escape routes, and note which logs function as shared habitat.

Identify Yellow-blotched Map Turtle from a riverbank
- Record the shell profile
- Use binoculars or a long lens to capture the high keel and yellow blotches on the carapace.
- Add head and body pattern
- Photograph the striped head and shell markings together, noting the turtle’s apparent size.
- Require Pascagoula context
- A natural observation should come from the Pascagoula River system, usually on sunny logs during warm weather.
- Let the basking log remain occupied
- Approach slowly and obliquely from durable ground; if one turtle drops into the river, stop before the rest flush.
Good to know
This species is not simply any striped river turtle in southern Mississippi; its range is the Pascagoula system and similar map turtles occur nearby. Photographs should document shell and head pattern without handling.
