What makes spider monkeys warm?

Spider monkeys are warm-blooded animals, meaning they maintain a constant internal body temperature regardless of the external environment. Here's how they achieve this:

* Metabolism: Like all mammals, spider monkeys have a high metabolic rate, which means they burn calories to generate heat.

* Fur: Their thick fur provides insulation, trapping a layer of warm air close to their skin.

* Behavior: Spider monkeys may huddle together for warmth, especially during colder temperatures.

* Sunbathing: They are known to bask in the sun to absorb heat.

It's important to note that spider monkeys live in tropical rainforests, where the temperature is generally warm. This means they don't need to expend a lot of energy to stay warm.

So, it's not a specific characteristic that makes spider monkeys warm, but a combination of internal processes and behavioral adaptations.
