The wood turtle (''Glyptemys insculpta'') is a turtle endemic to North America. It is in the genus ''Glyptemys'', a designation given to only one other turtle: the bog turtle. The wood turtle reaches a carapace length of , its defining characteristic being the pyramidal pattern on its upper shell. Morphologically, it is similar to the bog turtle, spotted turtle, and Blanding's turtle. The wood turtle exists in a broad range extending from Nova Scotia in the north (and east) to Minnesota in the west and Virginia in the south. In the past, it was forced south by encroaching glaciers: skeletal remains have been found as far south as Georgia. It spends a great deal of time in or near the water of wide rivers, preferring shallow, clear streams with compacted and sandy bottoms. The wood turtle can also be found in forests and grasslands, but will rarely be seen more than several hundred meters from flowing water. It is diurnal and is not overtly territorial. It spends the winter in hibernation and the hottest parts of the summer in estivation. The wood turtle is omnivorous and is capable of eating on land or in water. On an average day, a wood turtle will move , a decidedly long distance. Many other animals that live in its habitat pose a threat to it. Raccoons are over-abundant in many places and are a direct threat to all life stages of this species. Inadvertently, humans cause a large number of deaths through habitat destruction, road traffic, farming accidents, and illegal collection. When unharmed, it can live for up to 40 years in the wild and 58 years in captivity. ==Taxonomy== Formerly in the genus ''Clemmys'', the wood turtle is now a member of ''Glyptemys'', a classification that wood turtles share with only the bog turtle.〔 It and the bog turtle have a similar genetic makeup, which is marginally different from that of the spotted turtle, the only current member of the ''Clemmys'' genus.〔 It has undergone extensive name changes by various scientists over the course of its history. Today, there are several prominent common names for the wood turtle, including sculptured tortoise, red-legged tortoise, and redleg.〔 Although no subspecies are recognized, there are morphological differences in wood turtles between areas. Individuals found in the west of its range (areas like the Great Lakes and the Midwest United States) have a paler complexion on the inside of their legs and underside of their necks than ones found in the east (places including the Appalachian Mountains, New York, and Pennsylvania).〔 Genetic analysis has also revealed that southern populations have less genetic diversity than the northern; however, both exhibit a fair amount of diversity considering the decline in numbers that have occurred during previous ice ages. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「wood turtle」の詳細全文を読む スポンサード リンク
