Do dolphins drink water—or do they get hydrated another way? Gordy dives into the fascinating world of dolphin biology, osmoregulation, and marine mammal physiology to answer a surprisingly tricky question: how do dolphins survive surrounded by salt water? This episode explores metabolic water, reniculate kidneys, and the unique strategies dolphins use to stay hydrated in the ocean. Along the way, you’ll learn why drinking seawater is deadly for humans, how dolphins process salt differently, and why their hydration strategy has more in common with kangaroo rats than with us.
If you’ve ever wondered about dolphins, marine life, seawater drinking myths, or animal physiology, this episode will give you a science-packed answer you’ll want to share. Perfect for ocean lovers, biology buffs, and anyone looking for a conversation starter about the strange adaptations of life at sea.
So—what do dolphins drink? Watch to find out.
