Arachnula (a-rack-new-la), an amoeboid protist which may develop into very extensive organisms with many nuclei, and with an irregular branching appearance of both cytoplasmic tracts and pseudopodia. This is a typical cell. Phase contrast. This picture was taken by David Patterson, Linda Amaral Zettler, Mike Peglar and Tom Nerad from cultures and other materials maintained at the American Type Culture Collection during 2001.
