sea cucumbers clean and oxygenate the seafloor

Sea cucumbers are found everywhere from shallow shores to abyssal trenches 6,000 meters below sea level.On the deep sea floor, they comprise the majority of animal biomass,reaching up to 95% in some areas.As these sausage-shaped wonders trudge along, they vacuum up sand,digest the organic matter it contains, and excrete the byproduct.In this process, sea cucumbers clean and oxygenate the seafloor by breaking down detritus and recycling nutrients.
