Diagnosis:

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.  

  

Distribution:

Snapping Turtles are found throughout the United States, extreme southern Canada, and a small section of northern Mexico east of the Rocky Mountains.  In Nebraska they are found statewide, are considered common, and are not specially protected.  With the proper license, they may be hunted for their meat.

Natural History:

Snapping Turtles are predators that often use a “sit and wait” strategy to acquire food.   They remain motionless under water or buried in mud with their heads above the mud surface and strike viciously and quickly at passing prey – which is nearly anything they can catch.  Spring rains will often trigger migratory bursts, and Snapping Turtles can be found on land.  Their name is given to them because of their aggressive behavior on land, but in the water they are much calmer.  Usually they swim or walk slowly away when approached.  Mating can occur throughout the active season.  In ponds with high densities of turtles, males may fight each other for breeding privileges.  Females nest in May and June and can migrate a fair distance from water to lay their eggs.  Nesting activity is normally completed in the morning or evening.  Eggs are round and leathery and look like ping pong balls.  Young turtles hatch between August and October. Snapping Turtles can be found using any body of water from the channelized Missouri River to small intermittent streams and ephemeral ponds.  As water recedes from temporary streams and pools, these turtles migrate across grasslands, roads, and anything else in their way to find another body of water.  They also have been known to climb fences.
