The Common Snapping Turtle (Chelydra serpentina) is a large freshwater turtle of the family Chelydridae. Its natural range extends from southeastern Canada south, west to the Rocky Mountains (and beyond, where introduced), throughout Mexico, and as far south as Ecuador. This species and the larger Alligator Snapping Turtle are both widely referred to as snapping turtles or snappers (though the Common Snapping Turtle, as its name implies, is much more widespread overall).
Common snappers are noted for their belligerent dispositions when out of the water, their powerful beak-like jaws and their highly mobile head and neck (hence the specific name "serpentina," meaning "snake-like"). In some areas they are hunted heavily for their meat, a popular ingredient in turtle soup. These turtles have lived for up to 47 years in captivity, while the lifespan of wild individuals is estimated to be around 30 years.
Snappers will travel extensively overland to reach new habitat or to lay eggs. Pollution, habitat destruction, food scarcity, overcrowding and other factors will drive snappers to move overland; it is quite common to find them traveling far from the nearest water source. This species mates from April through November, with their peak laying season in June and July. The female can hold sperm for several seasons, utilizing it as necessary. Females travel over land to find sandy soil in which to lay their eggs, often some distance from the water. After digging a hole, the female typically deposits 25 to 80 eggs each year, guiding them into the nest with her hind feet and covering them with sand for incubation and protection. Incubation time is temperature-dependent, ranging from 9 to 18 weeks. In cooler climates, hatchlings overwinter in the nest.
Lifting the turtle with the hands is difficult and dangerous. Some snappers can -- and will -- stretch their necks halfway back across their own carapace to bite. Manual lifting (which should be done only if no other options are available) is best accomplished by sliding fingers behind the turtle's hind legs, with the tail between the hands, and gripping the turtle between the fingers and thumbs. The handler then proceeds to lift the turtle only just off the ground. The turtle will probably squirm and try to dislodge the handler's hands with its hind legs. Even a small snapper is relatively powerful for its size, with long sharp claws; further, due to their aquatic inclinations, these turtles are often slimy and wet, and they are good at causing prospective handlers to lose their grip. In any case that a snapping turtle must be handled, it is best to have the turtle on the ground or very close. Wild turtles may be covered with a smelly pond slime and may also defecate, urinate, or musk on a handler.
The Common snapper, known commonly and in folklore as the "Ograbme," was the central feature of a famous American political cartoon. Published in 1808 in protest at the Jeffersonian Embargo Act of 1807, the cartoon depicted a snapping turtle, jaws locked fiercely to an American trader who was attempting to carry a barrel of goods onto a British ship. The trader was seen whimsically uttering the words "Oh! this cursed Ograbme" ("embargo" spelled backwards). This piece is widely considered a pioneering work within the genre of the modern political cartoon.
The year 2006 saw the snapping turtle declared the "state reptile" of New York by a sweeping vote of the New York Legislature after being popularly chosen by the state's public elementary school children.
