Apalone spinifera

Identification

Spiny Softshells have a flat, smooth, leathery carapace (shell covering the back) that does not have scutes. The carapace is gray-brown with dark spots or rings. They get their name from the tiny soft spines on the anterior margin of their carapace. The plastron is narrow and pale yellow or white. The females carapace can be 10-19 inches long, while the males carapace is only 5-10 inches long. Softshells have a very long neck and a thin tubular snout. Their skin is tan or olive with black markings. They have two light stripes on the side of their face.
