The largest animals ever to have lived on Earth, blue whales are colossal in every respect — including, it must be said, their poop. When a blue whale goes, it goes big. It’s hard to judge absolute distances from the photo, but in scale the deposit is nearly as long as a full-grown blue whale.
While it looks a bit foul, whales are actually the ocean’s unappreciated gardeners, playing enormous roles in nutrient and carbon cycles. In short — or perhaps in long — their poop helps make the aquatic world go round.
Whales and marine mammals can fertilize their surface waters. This can result in more plankton, more fish, and more whales. Learn more here.
