Note that it’s illegal to capture wild turtles for keeping as pets in Missouri. But you’re allowed to hunt the softshell turtles and snapping turtles with just a fishing license.

In this article, we’ll look at each of these species of turtles in Missouri. For each species, we’ll look at basics such as physical appearance, average adult size, what they eat, where they live, lifespan, and more.

17 Types Of Turtles In Missouri

1. Alligator Snapping Turtle

• Scientific name: Macroclemys temminckii
• Common name: Alligator snapping turtle, Snapping turtle
• Family: Chelydridae
• Size: 15 to 26 inches
• Lifespan: 80 to 120 years
• Conservation status: Vulnerable

The alligator snapping turtle is the largest freshwater turtle in Missouri. This species is large than the common snapping turtle. An adult alligator snapping turtle weighs 15 to 20 inches long.

An alligator turtle is characterized by a long, tough shell with trigonal ridges that resemble the back of an alligator (hence the name alligator turtle). Shell coloring can be black, olive, or brown. Though some people believe that the green tips on the shell ridges are natural, they’re simply algae.

These alligator turtles also prefer living in deeper waters of rivers, canals, lakes, and swamps in Missouri.

As omnivorous species, they hunt their prey (but not actively). They have a unique way of hunting where they lie at the bottom of the water body and open their mouth to show their pink work-like appendage to lure their prey. And when the prey gets close enough, the turtle ambushes it!

Another interesting fact about this turtle is its powerful jaws which can bite with a force of up to 1000lbs!

Other adaptations of these turtles include webbed feed, long claws, and extremely flat shells that enable them to quickly swim away from predators and burry in the muddy bottom of the waters they reside in.
