Spiny Softshell Turtle
This month, we are highlighting our only Spiny Softshell Turtle, Tortilla, for World Turtle Day on May 23rd. When you observe him in our Great Lakes Future Exhibit, you’ll notice that his shell looks different from those of other aquatic turtles you’re familiar with. That’s because their carapace, or shell, is a softshell, offering them little protection from predators. Instead of relying on their shells for defense, they depend on their camouflage and burying skills. You’ll often find Tortilla buried in the substrate, with only his head poking out, unless he becomes frightened, in which case he’ll bury his head too.
Underwater Adaptations
Softshell turtles spend most of their lives in the water, so they have evolved several features to help them thrive underwater. They possess fully webbed feet, a long neck enabling them to breathe in shallow water while buried, and a snorkel-like nose facilitating underwater breathing. Moreover, they’ve developed finger-like tissues lining their throat that absorb oxygen from the water as they pump it in and out, allowing them to breathe underwater!
Large and in Charge
The Spiny Softshell Turtle ranks among the largest freshwater turtle species in North America, with shells reaching diameters of 5-21 inches and weights of up to 25 pounds. While the Softshell Turtle is not considered a Threatened Species, it still faces threats such as habitat destruction and chemical pollution in waterways.
