The correct answer is option 1 - Whales. Whales are warm-blooded animals because they have the ability to regulate their body temperature internally, regardless of the external environment. This ability is known as endothermy. Option 2, Whale Sharks, are not warm-blooded animals. They are actually cold-blooded, relying on external sources of heat to regulate their body temperature. Option 3, Alytes, are also not warm-blooded. They are a type of amphibian known as fire-bellied toads, which are ectothermic or cold-blooded. Option 4, Draco, refers to the genus of lizards known as flying dragons. Like other reptiles, they are also cold-blooded. Therefore, the correct answer is option 1 - Whales, as they are the only warm-blooded animal listed.
