◆ANNELIDA◆
They have a long and segmented body.
Annelids are bilaterally symmetrical.
They are triploblastic.
Also, they exhibit organ system grade of organisation, showing organ differentiation.
The body is covered with a thin cuticle.
They are coelomate. A body cavity or coelom is present.
Annelids live in moist environments, moist soil, freshwater and marine water.
They have parapodia and chitinous setae, used for locomotion.
Their body appears red due to the presence of haemoglobin.
Excretory and nervous systems are present.
The digestive system is complete and developed.
Respiration happens through the general body surface.
These invertebrates have a true closed circulatory system.
Sexes may be separate or united, wherein they are called hermaphrodites.
Fertilization can be internal or external.
◆PORIFERA◆
Their bodies consist of loosely organized cells.
They vary in size from less than a centimeter to a mass that can fill your arm.
They are asymmetrical or radially symmetrical.
They have three cell types: pinacocytes, mesenchyma cells, and choanocytes.
They have central cavity or spongocoel. This cavity may be divided into series of branching chambers. Water circulates through these chambers for feeding.
Numerous pores are present in the body wall. i.e. ostia and osculum
They have no tissue or organ.
Skeleton is composed of spicules.
Nervous system is absent but neurosensory cells are present.
Asexual reproduction takes place by budding.
They are hermaphrodites and larvae are produced during development

The body structure of sponges is designed in such a way that water moves through the body, where it can filter out food and also absorb the dissolved oxygen, along with eliminating waste material. Organisms belonging to this phylum do not have specialised digestive, nervous or circulatory system.♡♡♡
