adj.变温的

Fish are poikilothermic, which means their body temperature varies with the temperature of their environment.
鱼类是变温动物，这意味着它们的体温会随着环境温度的变化而变化。
Unlike mammals, poikilothermic animals do not have the ability to regulate their body temperature internally.
与哺乳动物不同，变温动物没有能力在体内调节体温。
The reptile's poikilothermic nature makes it particularly sensitive to changes in its surroundings.
爬行动物的变温特性使其特别容易受到周围环境变化的影响。
Poikilothermic animals often have a slower metabolism than warm-blooded animals because they don't need to maintain a constant body temperature.
变温动物的新陈代谢通常比恒温动物慢，因为它们不需要保持恒定的体温。
The snake basked in the sun to raise its body temperature, a common behavior for poikilothermic reptiles.
蛇在阳光下晒太阳以提高体温，这是变温爬行动物的常见行为。
In cold environments, poikilothermic animals may become torpid or enter hibernation to conserve energy.
在寒冷的环境中，变温动物可能会变得昏昏欲睡或进入冬眠状态以节省能量。
Many fish species are poikilothermic and rely on external sources of heat to regulate their body temperature.
许多鱼种是变温动物，依靠外部热源来调节体温。
The lizard's poikilothermic nature makes it particularly vulnerable to extreme temperatures.
蜥蜴的变温特性使其特别容易受到极端温度的影响。
Unlike birds, which are endothermic, poikilothermic animals cannot generate internal heat to stay warm.
与鸟类不同，鸟类是内温性的，而变温动物不能产生内部热量来保暖。
The turtle's poikilothermic metabolism slows down during the winter months, allowing it to survive on stored body fat.
海龟在冬季月份的变温新陈代谢会放慢，使其能够靠储存的体脂生存。
