This creates the conditions for sea grass beds and shellfish to thrive.Sea cucumber excretions can also aid in coral formation and may play a role in buffering marine environments from ocean acidification.As the ocean vacuum cleaners, they are very good at their job:about half of the sandy seafloor is thought to have passed through the digestive tract of a sea cucumber.So next time you're rejoicing in the feeling of sand crunching between your toes, consider this:those very grains of sand might have, at one point or another,been excreted by a pickle that breathes through its butt.
