变温动物

温度是影响变温动物生理活动的重要因素之一。

Temperature is an important factor affecting physiological activity of ectotherm .

昆虫是变温动物，气候变化是造成种群季节消长的基本原因之一。

Climate change will often lead to the fluctuation of insect populations , because insect is poikilothermic animals .

鱼类是变温动物，环境温度对鱼类的生理机能产生极其深刻的影响，研究鱼类对温度的适应性对鱼类的驯化与培育具有重要的意义。

Fishes live in water , and therefore the temperature of water has great influence on the physiological function of the fish .

因为恐龙属于爬行动物，而现代的爬行动物都不属于恒温动物，所以长期以来恐龙都被当作是变温动物。

Because dinosaurs were reptiles , and modern reptiles are not endotherms , it was long assumed that dinosaurs were not endotherms .

水蛭是变温动物&即是不能依靠自身而必须靠周围环境来维持恒定体温的冷血动物。

Leeches are ectotherms & cold-blooded animals that cannot regulate their own temperature and depend on their environment to do it for them .

因此又出现了恒温动物（即保持恒定体温的动物）和变温动物（即体温随外界环境的变化而改变的动物）这一区分方式。

Therefore the next distinction was made between animals that maintain a constant body temperature , called homeotherms , and those whose body temperature varies with their environment , called poikilotherms .

由于鱼类属于变温动物，与哺乳动物胶原相比拥有独特的氨基酸组成，因此鱼皮胶原蛋白有若干特殊性质。

Fish , a typical kind of poikilotherms , has the unique collagen which is different from that of terrestrial animals . The fish collagen has unique amino acid composition as well as some special properties .
