(b) Coelom. It is a mesoderm lined, fluid-filled internal body cavity that provides a shock proof environment
to the contained body organs, e.g., annelids, chordates.
(c) Triploblastic. They are animals having three germinal layers – outer ectoderm, middle mesoderm and
inner endoderm, e.g., liver fluke/ Ascaris / Pheretima/house fly/star fish/Amphioxus cat.
