Tags: warm-blooded, cold-blooded, animals, amphibians, mammals, difference
Ever wondered what really makes warm-blooded creatures different from the cold-blooded ones. Here are the details.
| | Warm-blooded keep the inside of their bodies at a constant temperature by generating their own heat when they are in a cooler environment, and by cooling themselves when they are in a hotter environment.
Cold-blooded take on the temperature of their surroundings. They are hot when their environment is hot and cold when their environment is cold. |
| | Warm-blooded to stay cool, warm-blooded animals sweat or pant to loose heat by water evaporation.
Cold-blooded often like to bask in the sun to warm up and increase their metabolism. When too hot, it will go into a shady area, open its mouth wide, lighten its skin color or burrow into cool soil. |
| | Warm-blooded can remain active in cold environments.
Cold-blooded can hardly move. |
| | Warm-blooded can live in almost any surface environment on Earth, like in arctic regions or on high mountains.
Most cold-blooded would have difficulty surviving. |
| | Warm-blooded can remain active, seek food, and defend themselves in a wide range of outdoor temperatures.
Cold-blooded can only do this when they are warm enough. |
| | Cold-blooded require much less energy to survive.
Warm-blooded require much more food and energy. |
| | Small Warm-blooded need to eat very often to survive because they need more energy to keep a constant body temperature.
Cold-blooded do not have to burn a lot of food to maintain a constant body temperature, and they are more energy efficient and can survive longer periods without food. |
| | Warm-blooded bodies provide an warm environment for viruses, bacteria and parasites to live in.
Cold-blooded's constantly changing body temperatures make life more difficult for invaders. |
| | Warm-blooded have developed a stronger immune system.
Cold-blooded's immune system is more efficient when the animals is warmer, however, since bacteria probably grow more slowly in lower temperatures, reptiles sometimes lower their body temperatures when they have an infection. |
