Mention the appendages involved in the locomotion of a typical annelid
  • 1 answers

Meghna Thapar 4 years, 3 months ago

All annelids except leeches also have chitonous hair-like structures, called setae, projecting from their cuticle. Sometimes the setae are located on paddle-like appendages called parapodia. Annelids are schizocoelous and with a large and well-developed true coelom (i.e., one that is lined with mesoderm). The basic features of locomotion in annelids are most easily observed in the earthworm because it lacks appendages and parapodia. Movement involves extending the body, anchoring it to a surface with setae, and contracting body muscles. ... The setae are retracted during the circular contraction period.
