Microscope footage of the polychaete worm Pygospio elegans. This is a marine bristle worm that inhabits sand and mud in coastal regions of the northeastern Atlantic, as well as the Mediterranean Sea and north Pacific. It inhabits a tube in the substrate, and extends its body and head from the tube to feed on detritus and smaller animals. It is known for its incredible ability to regenerate, and a worm cut in half may develop into two complete new worms. It can reach a length of around 15 millimetres. Sample collected from Dale, Pembrokeshire, Wales, UK. Filmed with darkfield illumination.
