Warm blooded vs. cold blooded

O.k. I know I should've learned this in school, but it's still confusing to me. Don't laugh! What's the difference between warm and cold blooded?

  • Humans are warm-blooded, and we can regulate our own body temp, cold-blooded animals can't. That's why lizards, snakes, and alligators, etc sunbathe.

  • that's just putting it in a very broad, simplistic explain.

  • Easiest way to think of it is this way: mammals (humans, whales, primates) are warm blooded. They have the ability to keep themselves warm even when it's cold out. I think it's called Thermal regulation. Snakes, turtles, tortoises are cold blooded and need to bask in the sun to regulate their body temperature.

  • Like the other posters said cold-blooded animals can't self regulate their temperature. If their body gets to cold they find the sun if it gets to warm they move to the shade. Unlike warmblooded animals who's temperature stays the same no matter what the outside conditions are. Even if you are in the middle of the North pole your temp is still around 98.6.

  • But Mommie, that isn't entirely accurate.

    Humans can and do suffer from hypothermia if we get too cold. That is why they always warn people to be careful when it's cold out.

  • Just for fun: "Some animals do not fall neatly into the categories of being warm or cold-blooded. Bats, for example, are mammals who cannot maintain a constant body temperature and cool off when they are not active. Echidnas maintain a range of body temperatures which usually lies between 77 and 98.6 degrees Fahrenheit and have difficulty cooling down. Mole Rats are another group of mammals who are unable to regulate their body temperature, however, since they live underground, the temperature of their environment does not change much. Some warm-blooded animals, such as bears, groundhogs, gophers and bats hibernate during the cold winter. During hibernation these animals live off of stored body fat and can drop their body temperatures by as much as 50 degrees Fahrenheit."
