Keeping Your Cool - Thermoregulation

from Ask A Biologist Podcast Hosted by Dr. Biology Talks with Dale DeNardo and Arno Vlooswijk

After a long hot summer, it seemed like a good time to see how some animals keep cool in extreme heat and stay warm when it is freezing outside. One animal even uses fiber optics to stay warm when the temperatures are below zero. Dr. Biology talks with biologist Dale DeNardo and engineer and thermographic artist Arno Vlooswijk about what's hot and what's not when it comes to thermoregulation. After listening to this episode, you can read more about how animals control their body temperature in our section on Python Thermoregulation, which includes our video - Life in the Cold.
