Most animals alive today are cold-blooded, or "ectotherms". Insects, worms, fish, crustaceans, amphibians and reptiles—basically all creatures except mammals and birds—are ectotherms.

Cold-blooded animals, including reptiles like snakes and lizards, depend on outside sources to control their temperature: For example, basking in the sun to warm up.

The first warm-blooded animals appeared abruptly 233 million years ago, according to clues hidden deep inside their ears. Before now, scientists estimated that warm-bloodedness, or endothermy ...

In fact, they may have been warm-blooded, new research suggests. Dinosaurs may not have been the slow, sunbathing reptiles researchers used to think. IE 11 is not supported.

Dinosaurs were initially cold-blooded, but global warming 180 million years ago may have triggered the evolution of warm-blooded species, a new study found.
