Biology

Thermoregulation and Evaporative Cooling in Desert Kangaroo Rats

Quick fact

Kangaroo rats can live their entire lives without drinking a single drop of water, deriving all their moisture from the metabolic breakdown of dry seeds and using a nasal cooling system that recovers up to 80% of the water normally lost during breathing.

Why this is interesting

Imagine living in a place where water is scarcer than gold, yet you never take a sip. How do desert kangaroo rats not only survive but thrive in the scorching Mojave and Sonoran Deserts?
