poikilothermic

Unlike most terrestrial animals, aquatic animal species used for human consumption are poikilothermic, meaning their body temperatures vary according to ambient temperatures..与大多数陆地动物不同，供人类消费的水生动物为冷血品种，也就是说它们的体温会根据环境温度而变化。

These indeed have new comparative features in terms of the tolerance, comparing with the organisms that do not need to maintain homeostasis, such as poikilothermic organisms..这与那些不需要保持内稳态的生物如变温生物相比，的确在耐受性方面存在新的比较特点。

Amphibians and reptiles are poikilothermic and quite sensitive to the change of ambient temperature. They adapt to environmental temperature by means of self- thermoregulation ..两栖类和爬行类属于变温脊椎动物，它对外界环境温度的变化非常敏感，借助自身体温调节以适应或抵抗这种变化。
