1. Homeotherms are " not " necessarily endothermic.2. Animals also tend to be homeotherms which are animals that maintain a high temperature. 3. Some homeotherms may maintain constant body temperatures through behavioral mechanisms alone i . e . behavioral thermoregulation. 4. For the same body weight, poikilotherms need only 5 to 10 % of the energy of homeotherms . 5. As a result, poikilotherms often have larger, more complex genomes than homeotherms in the same ecological niche. 6. Like homeotherms , poikilotherms and ectotherms usually exhibit a thermal preference, although not quite in the same way. 7. This affects poikilotherms and ectothermic homeotherms ( " cold-blooded " animals ) as well as endothermic homeotherms. 8. This affects poikilotherms and ectothermic homeotherms ( " cold-blooded " animals ) as well as endothermic homeotherms . 9. The results suggest the samples are " large pieces of vertebrate skin . . . from a huge homeotherm ". 10. Crawford's gray shrew is one of the smallest desert mammals and one of the world's smallest homeotherms .
