Spiny Softshells have a flat, smooth, leathery carapace (shell covering the back) that does not have scutes. The carapace (shell covering the belly) 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.
Softshells are entirely aquatic and are very fast in the water. They also bask often. In Vermont they are found only in the Northeast corner of Lake Champlain near the Lamoille and Missisquoi River deltas.
This species has a state natural heritage rank of S1 (very rare). The Spiny Softshell has been designated a Species of Greatest Conservation Need (high priority) in Vermont’s Wildlife Action Plan, and is threatened in Vermont. Please report all sightings of this species in Vermont. Take photos if possible. Even historic sighting information is useful.
