Kinorhyncha sp.

Note: These very tiny crawling worms, mostly less than a few millimeters in length, live in mud and sand, and are a member of the meiofauna found in healthy substrates/sandbeds. They look like very small somewhat flattened crustaceans and have a tail used for steering through their burrows. Most are a dull yellowish-brown in color and feed upon organic debris. A valuable addition to sandbeds. Other drawings/sketches of such worms can be seen in the book "Encyclopedia of Marine Invertebrate," Edited by Jerry G. Wells, ISBN #0-87666-495-8, page 179, or "Marine Life" by David & Jennifer George, ISBN #0-4471-05675-8, page 47.
