Annelids gallery

Annelids are worm-shaped animals with bodies segmented into several rings that repeat identically. (Ann- from Latin annullus = ring). Only the segments of the front part (the head) and the rear are different. Errantia annelids are segmented worms that live freely on sand, mud or among rocks. They have parapods and often well developed bristles that allow them to move. Sedentaria annelids are worms that secrete calcareous, chitinous or mucous tubes fixed on rocks, weeds, shells or buried in sand or mud. Occasionally, they can get out of their tube and move around.
