If you go to a zoo on a cold day and watch the snakes, you’ll see what it means to be coldblooded. Not much action going on — most reptiles and other coldblooded creatures take on the temperature of their surroundings, so they tend to be most sluggish when the outside temperature is cool. The monkeys, however, act like they’ve had one too many cappuccinos. That’s largely because they’re warmblooded — their bodies have lots of tricks for actively generating heat and losing it, so they’re metabolically able to move quickly and maintain their core temperature no matter how hot or cold it is outside.
