Nebraska’s largest turtle, the Snapping Turtle has a unique set
of characteristics. The large head,
remarkably long tail, and highly reduced plastron make it easy to
identify. The carapace can be brown,
gray, or nearly black, and there are three prominent longitudinal peaks or
keels along its center as well as a series of “sawtooth” projections from the
posterior marginal scales. Keels may be
worn smooth in older individuals.
Sometimes the carapace may appear green as a result of algae that take
up residence there. Average carapace
lengths in Nebraska are 9.0-10.0 inches (22.8-25.4 cm) with specimens up to
15.0 inches (38.1 cm) being reported.
Weights up to 50.0 lbs (22.6 kg) are possible; however, most are much
smaller in size.
