How do poriferan animals differ from coelenterate animals?

Dear Student

(1) Animals from Porifera show cellular level of organisation, while those from Coelenterata show tissue level of organisation.
(2) In Porifera there is no division of labour, while in Coelenterata some division of labour is seen.
(3) Porifera do not have coelom, while coelenterata have coelom.

​Thanks
