Deep-sea footage reveals plastic eaten by tiny plankton sinks to the bottom in fecal pellets
Over the last decade, researchers have discovered tiny pieces of plastic in the ocean and even in deep-sea mud, but they don't much about how microplastics are transported within the ocean.
But now, new research has found that filter-feeding animals called giant larvaceans can collect and consume microplastic particles in the deep sea.
The plastic particles accumulate in larvaceans' cast-off filters and are passed into the animals' fecal pellets, which sink to the ocean floor, potentially carrying microplastics to the ocean floor with them.
