How Orcas Get Freshwater

Orcas spend their lives in the ocean, surrounded by saltwater, yet they still need freshwater to survive. Instead of drinking seawater like a thirsty human might imagine, they obtain much of the water their bodies need from their prey, along with water produced during metabolism. Their kidneys help them manage the salt they take in through food and seawater exposure. In human care, orcas receive carefully managed diets and access to appropriate hydration, but the claim that keepers routinely feed them large blocks of ice as their main way to stay hydrated should not be assumed without evidence. These ocean predators have specialized ways of maintaining their water balance in a salty environment. Disclaimer: This video is shared for educational purposes.
