difference between arthropoda and mollusca south african institute of technology

Poda means Appendages .Therefore it is clear that Arthropods have jointed appendages whereas Molluscs do not have jointed appendages. Arthropods have a Chitinous exoskeleton while Molluscs have a calcareous exoskeleton (if present). Most Arthropods undergo Ecdysis/Moulting The intertidal zone is also home to several species from different phyla (Porifera, Annelida, Coelenterata, Mollusca, Arthropoda, etc.). During locomotion, these rods provide support by stiffening the body. Chordates are all organisms that possess a notochord at one or more stages during their growth. Growth is confined to periods when the exoskeleton is shed and a new, larger one is produced. Spatial difference, such as one species inhabiting treetops while another species lives at ground level, is another reason why species develop. Their common name praying mantis is derived from the distinctive posture of the first pair of legs that can be observed in animals in repose.
