The Surprisingly Big Business of Toad Poop 💩 🐸 Toads may not get much spotlight, but their biology is endlessly fascinating, right down to the way they poop. Amphibians like this one excrete waste through the cloaca, a single opening used for digestion, reproduction, and urinary functions. Their droppings can be surprisingly large relative to body size, as seen here, because their digestive systems absorb most of the water from food before expelling the solid waste.
