Just like any other animal, sharks have to eat in order to stay alive–and that means something is going to exit their body from the opposite end. Much like other animals, they defecate in short spurts as needed.
What Does A Shark Poop Look Like?
Shark poop is mostly liquid but can include solid waste. When a shark excretes, it appears as a dramatic cloud of color in the water, typically yellow or green.
The poop’s color comes from the digestion of food, mixing broken-down muscle and blood pigments with green bile. Water depth might also affect the visible color.
How Do Sharks Poop?
Once a shark has broken its meal down in the spiral intestine and colon, the leftover waste passes into the rectum and leaves the body through the cloaca, the single opening sharks use for waste and reproduction. Scientists have filmed sharks twisting and flexing their bodies as they defecate, motions that seem to help force the feces out.
How Often Do Sharks Poop?
Sharks eat a lot, so they poop a lot, too. There are no exact studies on the frequency, but the waste amount varies based on their food intake and type.
What Happens To Shark Poop Underwater?
Shark poop helps feed the wider ocean and supports coral reefs by carrying carbon, minerals, and nutrients in from off-shore waters. It plays a key part in the ocean’s nutrient cycle and gives researchers a useful window into shark health.
