Sharks - cold-blooded, or ectothermic animals. This means that the temperature of the body of sharks is regulated by environmental conditions. Mammals are warm-blooded animals. Their temperature remains constant, despite fluctuations in environmental conditions. Warm-blooded animals, also commonly called endotherms, have an adaptation that helps them maintain a constant body temperature. Such adaptations include shaking and protective wool cover.
