Phylum Annelida -

  • The term ‘Annelida’ is derived from the latin term annellus, that implies small rings. This phylum contains the animals that are also called ‘Ringworms’.
  • The body of annelids is truly segmented because these segments or metameres are externally visible as annuli and internally as septation. 
  • Segmentation improves the movement and enhances the chances of survival by providing redundancy.
  • They are triploblastic and bilaterally symmetrical. 
  • They have a true coelom, i.e., they are coelomate. The mesoderm lines the cavity on both sides.
