"Warm-blooded" is used to describe animals that generate their own heat. Warm-blooded creatures are often called ectotherms. Mammals and birds are warm-blooded; reptiles and amphibians are cold-blooded.Know More
Reptiles and other cold-blooded animals must draw heat form the environment, and they are slower and less active when the temperature drops. They also have a slower metabolism, which is why they often spend long periods of time resting. However, being cold-blooded has an advantage: they do not have to eat as much as their warm-blooded counterparts.
In exchange for their more robust dietary demands, warm-blooded animals are able to cope with a broader range of environmental conditions, but hotter weather is often a greater threat than cold weather. Warm-blooded creatures are able to move at a faster rate of speed than cold-blooded ones. This is part of the reason why mammals and birds can migrate long distances.
Some creatures, however, are not clearly warm-blooded or cold-blooded. The dinosaurs, in particular, seem to straddle this gap. If they were strictly cold-blooded, they would have been far slower than most experts believe. If they were warm-blooded, their dietary needs would have been more than most think is realistic. While there is still a considerable amount of debate, many experts now believe that dinosaurs were neither truly warm-blooded nor cold-blooded.Learn More

Most extinctions can be prevented by implementing conservation strategies such as legal remedies, preserving natural plant and wildlife habitats and using synthetic medicines not derived from plant and animal products.
