    • The body has definite number or segments.
    • The tentacles, parapodia and setae are totally absent.
    • They are hermaphrodite.
    • Fertilization: internal and a larval stage is absent.
    • Examples: .Hirudinaria (Leech)
    • always with 34 segments
    • parasitics or predators

  • Annelida is divided into three classes, which are Polychaeta, Oligochaeta, Hirudinea.

    • Annelida is invertebrates (no backbone).

    • Exist in various environments including marine waters, fresh waters and also in moist terrestrial areas.

    • The body is segmented which is the most distinguishing feature of annelids.

    (Polys: many; chaite:hair)

    • Habitat: They are marine, terrestrial, and freshwater.
    • Bilaterally symmetry, segmented worms.
    • Archetypical protosome development (schizocoely).
    • True coelomates (schizocoelomates).
    • Lateral epidermal setae with each segment.
    • Dioecious or hermaphroditic.
    • Fertilization: external
    • Other Examples: Syllis, Sabella
