What mammal has ectothermic tendencies?

The mammal that has ectothermic tendencies is the naked mole rat.

While all mammals are endothermic (meaning they generate their own body heat), the naked mole rat has unique adaptations that allow it to behave in a way that is similar to ectothermic animals.

Here's why:

* Low metabolic rate: They have a lower metabolic rate than most mammals, meaning they don't produce as much heat internally.

* Social thermoregulation: Naked mole rats live in large colonies with complex social structures. They huddle together for warmth, relying on the collective body heat of the group.

* Limited shivering: They have a limited ability to shiver, which is the main way most mammals raise their body temperature.

* Behavioral thermoregulation: They seek out warm microclimates and minimize heat loss through burrowing and huddling.

While not strictly ectothermic, these adaptations allow them to conserve energy and tolerate a wide range of environmental temperatures, making them unique among mammals.
