If you walk over the flats during low tide, you often see the top ends of the Pygospio elegans worms sticking out of the soft bottom. During high tide, two tentacles extend out of the tube which the worm uses to scrape the bottom. The vibrating hairs on the tentacles carry the food to the mouth. This worm is also capable of catching food with its appendages and by producing a mucus with its tube. Pygospio elegans is not tolerant to severe winters.
