poikilotherm การใช้

Tundra is largely devoid of poikilotherms such as frogs or lizards.
For the same body weight, poikilotherms need only 5 to 10 % of the energy of homeotherms.
Similarly, the fauna are invertebrate poikilotherms, with the largest being broadly analogous to reptiles on Earth.
For an important chemical reaction, poikilotherms may have four to ten enzyme systems that operate at different temperatures.
As a result, poikilotherms often have larger, more complex genomes than homeotherms in the same ecological niche.
