现存爬行动物的全球分布比哺乳动物或鸟类更为有限，高纬度地区爬行动物物种多样性较低。这种有限的地理分布的核心是爬行动物的恒温特性，这意味着它们通常在寒冷的温度下变得迟钝。然而，在这里，我们报告了在高纬度的冷水中潜水的棱皮龟（Dermochelys coriacea）的第一次详细的遥测。一个人带着卫星标签，可以传递温度-深度信息，连续潜入低至0.4摄氏度的地下水域数周。全球变暖可能会使棱皮龟的觅食范围进一步扩大到温带和北方水域。(c) 2006 Elsevier B.V.版权所有
The global distribution of extant reptiles is more limited than that of mammals or birds, with low reptilian species diversity at high latitudes. Central to this limited geographical distribution is the ectothermic nature of reptiles, which means that they generally become torpid at cold temperatures. However, here we report the first detailed telemetry from a leatherback turtle (Dermochelys coriacea) diving in cold water at high latitude. An individual equipped with a satellite tag that relayed temperature-depth profiles dived continuously for many weeks into sub-surface waters as cold as 0.4 degrees C. Global warming will likely increase the foraging range of leatherback turtles further into temperate and boreal waters. (c) 2006 Elsevier B.V. All rights reserved.
