A new study reveals that baleen whales, including humpbacks and gray whales, enrich oceans when they take a whizz.

The study focused on a handful of baleen species — namely, gray whales, humpback whales and right whales — which display “traditional migratory patterns,” moving from colder waters in the summer to warmer waters in the winter. For example, humpbacks in the North Pacific migrate annually from the Gulf of Alaska to the coast of Hawaii.

In a nutshell Migrating baleen whales transport thousands of tons of nutrients from cold, nutrient-rich feeding grounds to warm, nutrient-poor breeding areas through their urine, placentas, skin, and carcasses,

Now we can add whale urine to that list, according to a paper published in the journal Nature Communications. “Lots of people think of plants as the lungs of the planet, taking in carbon dioxide, and expelling oxygen,

Baleen whales undertake some of the longest migrations of any mammal, traveling thousands of miles between nutrient-rich feeding grounds and tropical breeding areas. Southern Hemisphere humpback whales make seasonal journeys of over 5,
