In the southern United States, snakes can be vibrant and bright. In the North, they tend to be dark and drab. A dark coat may seem a bit depressing. It may, however, help northern snakes soak up heat from the sun more quickly than their southern kin, a teen finds. And a quick solar heating could prove an advantage in colder climes.在美国南部，那里的蛇需要收到响声，而且很颜色艳丽。在北方，这些蛇会偏向于变为黑色或者浅褐色。

Darker colors might help snakes soak up the sun’s warmth.吉安娜·范泰尔对蛇十分感兴趣，她找到蛇所处的地点越是往北，它们的颜色比南方的蛇就更深。加深的颜色也许可以协助蛇更佳地提供太阳的温度。
