又叫温血动物。体温不因外界环境温度而改变,始终保持相对稳定的动物,叫做
恒温动物
。如绝大多数鸟类和哺乳动物。
具有与外界温度或自身活动无关而保持一定体温特征的动物,亦即为恒温性(homeo-thermism homeothermy)发达的动物。鸟类和哺乳类属
恒温动物
,体温随种类而异,大多在36╠42℃的范围内。一般小形的动物较大形的体温为高,昼行性动物的体温清晨最低,到傍晚升高。但体温调节能力高的动物(食肉类、马、人等)一天之内体温变幅不超过1℃。低等哺乳动物的体温一般较低,可随外界温度或活动状态有显著的变化,这种状态称为变温性(heterothermism heterothermy)。
恒温动物
的特征是产热的能力大,具有毛、羽和皮下脂肪等的隔热构造,体温调节的能力发达,能随体内外的温度条件通过产热或散热进行调节。在正常的体温下,
恒温动物
的物质代谢效率最高,而当体温超越正常的范围时诸机能就会显著地失调甚至招来致命的结果。恒温性是体内平衡调节的典型特征,能获得这种性能的动物其分布范围就能扩大,可一年四季进行活动。不过在极端严寒的季节或食物不足时,由于体温保持困难,有的就采取冬眠的方式以适应这种环境的变化。
