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,

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,

“Beyond urine, whale carcasses also serve as nutrient deposits. When a whale dies, its massive body sinks to the ocean floor, creating a ‘whale fall’ — an event that supports entire deep-sea communities. Scavengers like sharks, hagfish, and deep-sea invertebrates feast on the remains, recycling nutrients back into the ecosystem.”
