These seeps provide food from chemical energy and structure for deep-sea animals to live on, increasing the biodiversity at such sites. This image shows a mass of snails (gastropods called Neptunea) and their egg masses (the yellow towers) using clumps of tubeworms as a place to anchor at a seep site within Olympic Coast National Marine Sanctuary, off the Oregon coast.</p></div> </div> </div>
