Which one of the following pairs of animals is warm blooded?

Result
Your answer: —  Â·  Correct: D
Explanation

Warm-blooded animals, or endotherms, maintain a constant internal body temperature through metabolic processes regardless of environmental changes [1]. This group primarily includes birds and mammals [1]. In the given options, the peacock is a bird and the camel is a mammal, making them both endothermic [2]. Conversely, reptiles like crocodiles and tortoises, and fish such as hagfish and dogfish (a type of shark), are ectothermic or cold-blooded, meaning their body temperature fluctuates with the surroundings [3]. While some large sharks show minor endothermic adaptations, they are generally classified as ectotherms. Therefore, only the pair consisting of a bird (Peacock) and a mammal (Camel) satisfies the criteria for being warm-blooded [1].
