Sabella pavonina, commonly known as the peacock worm, is a species of marine polychaete worm in the family Sabellidae. It can be found along the coasts of western Europe and the Mediterranean Sea, in shallow, tidal waters with a bed of mud, sand or gravel. The worm is 10 to 25 centimetres (4 to 10 inches) in length, with its body divided into 100 to 600 small segments. The head has two fans of 8 to 45 feathery radioles arising from fleshy, semi-circular lobes. The body is mostly grey-green while the radioles are brown, red or purple with darker bands. This group of S. pavonina worms was photographed with a short-snouted seahorse in a protected marine natural area near Porto Cesareo, Italy.
