Birds and mammals are examples of endothermic animals.
鸟类和哺乳动物是恒温动物的例子。
Endothermy allows these animals to maintain a constant body temperature in varying environmental conditions.
恒温性使这些动物能够在变化的环境条件下保持恒定的体温。
In contrast, ectothermic animals rely on external sources for warmth, such as the sun or the ground.
相比之下，变温动物依赖外部热源，如太阳或地面来保暖。
The metabolic costs of endothermy can be quite high, but they offer significant advantages for survival in cold climates.
恒温性的代谢成本可能相当高，但在寒冷气候中生存却有显著优势。
Some endothermic fish have developed mechanisms to regulate their body temperature, despite living in aquatic environments.
一些恒温鱼类已经发展出了调节体温的机制，尽管它们生活在水生环境中。
The ability to generate internal heat is a key feature of endothermy that distinguishes it from ectothermy.
能够产生内部热量是恒温性区别于变温性的关键特征。
Endothermic animals often have more complex physiological systems to manage their body temperature.
恒温动物通常具有更复杂的生理系统来管理其体温。
The evolution of endothermy in mammals and birds is thought to be linked to their large brain sizes and high metabolic rates.
哺乳动物和鸟类的恒温进化被认为与其大脑大小和高代谢率有关。
While endothermy provides many benefits, it also requires a constant supply of energy to maintain a stable internal environment.
虽然恒温性提供了许多好处，但它也需要持续的能量供应来维持稳定的内部环境。
Many endothermic reptiles, such as some species of lizards and snakes, have developed behavioral adaptations to cope with temperature fluctuations.
许多恒温爬行动物，如某些蜥蜴和蛇的物种，已经发展了行为适应措施来应对温度波动。
