“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.”
