锦龟
Painted Turtle
「The painted turtle is the most widespread…」
The painted turtle is the most widespread native turtle of North America. This turtle is a member of the genus Chrysemys, which is part of the pond turtle family Emydidae. Fossils show that the painted turtle existed 15 million years ago. Three regionally based subspecies evolved during the last ice age. The southern painted turtle (C. dorsalis) is alternately considered the only other species in Chrysemys, or another subspecies of C. picta.

锦龟 是泽龟科锦龟属的其中一种，也可稱為油彩龜，生活在流速慢的淡水中，分布范围从加拿大南部到美国路易斯安那州和墨西哥北部，另外在大西洋和太平洋也有分布。化石表明锦龟早在1500万年前就已存在，由以区域划分的四个亚种（东部、中部、南部和西部锦龟）在末次冰期期间进化而来。成年雌性锦龟体长约10至25厘米（4至10英寸），重约300至500克（11至18盎司），而雄龟体型则相对较小。龟壳平滑，椭圆形、平底。皮肤呈橄榄色至黑色，四肢和头部有红、橙、黄条纹。

The painted turtle is a bottom-dwelling hunter. It quickly juts its head into and out of vegetation to stir potential victims out into the open water, where they are pursued. Large prey is ripped apart with the forefeet as the turtle holds it in its mouth. It also consumes plants and skims the surface of the water with its mouth open to catch small particles of food. Although all subspecies of painted turtle eat both plants and animals (in the form of leaves, algae, fish, crustaceans, aquatic insects and carrion), their specific diets vary. Young painted turtles are mostly carnivorous and as t
🏠照料
To thrive, painted turtles need fresh waters with soft bottoms, basking sites, and aquatic vegetation. They find their homes in shallow waters with slow-moving currents, such as creeks, marshes, ponds, and the shores of lakes. The subspecies have evolved different habitat preferences. The eastern painted turtle is very aquatic, leaving the immediate vicinity of its water body only when forced by drought to migrate. Along the Atlantic, painted turtles have appeared in brackish waters. They can be found in wetland areas like swamps and marshes with a thick layer of mud as well as sandy bottoms w

Species of reptile The painted turtle (Chrysemys picta) is the most widespread native turtle of North America. This turtle is a member of the genus Chrysemys , which is part of the pond turtle family Emydidae. Fossils show that the painted turtle existed 15 million years ago. Three regionally based subspecies (the eastern, midland, and western) evolved during the last ice age. The southern painted turtle (C. dorsalis) is alternately considered the only other species in Chrysemys , or another subspecies of C. picta . It lives in relatively slow-moving fresh waters, from southern Canada to north
