遷徙的鬚鯨是為海洋散播營養物質的重要角色。牠們在從營養豐富的覓食地前往營養低的繁殖地的同時，會透過尿液、幼鯨的糞便甚至牠們的屍體運送並釋放營養物質；這有助於促進浮游植物的生長，為沿海地區及珊瑚礁等提供養分。
Migrating baleen whales play a crucial role in transporting nutrients in the ocean.When they travel from nutrient-rich feeding grounds to low-nutrient breeding grounds, they release nutrients in their urine, calf feces and even carcasses; this help enhancing phytoplankton growth, fertilizing coastal and coral reefs.
