Discover Nature: Spiny Softshell Turtles Lay Eggs

A spiny softshell turtle with olive, elongated head; ovate, spotted brown shell; webbed feet sits in a shallow pool of clear water with mud bottom.
A spiny softshell turtle’s head emerges from a shallow pool of water. Spiny softshell turtles lay eggs in Missouri this week on sand- and gravel bars along streams and ponds.

Take a canoe or kayak out on a local pond or stream this week, and you’ll likely encounter spiny softshell turtles (Apalone spinifera).

Well-equipped for aquatic life, these turtles have a flat, round, smooth upper shell covered with skin; webbed toes, and a long, tubular snout that functions like a snorkel.

The shell – 5 to 17 inches in length – has small bumps or spines on the front of the upper shell and a small ridge on each side of the snout. Shell color varies with gender and age, but ranges from olive to tan, with brown and gray blotches.

Softshells eat a variety of aquatic animals, including crayfish, insects, snails, tadpoles, and fish — but they don’t threaten Missouri’s game fish populations.

This week near water, watch for spiny softshell turtles laying eggs in nests on sand- and gravel bars near water. These will hatch from late August to October.

Classified as a game species in Missouri, softshells have delicious meat. Check Missouri’s Wildlife Code for season dates, acceptable methods, and daily limits.
