Answers
Explanation:
Characteristic Features of Phylum Porifera
They are generally marine aquatic organisms, with a few freshwater species.
Their bodies are asymmetrical.
Body shape can be cylindrical, vase-like, rounded or sac-like.
They are diploblastic animals with two layers, the outer dermal layer and the inner gastral layer.
What are the characteristics of phylum Porifera?
These are pore-bearing multicellular animals.
The body has no organs.
They exhibit holozoic nutrition.
The body is radially symmetrical.
They can regenerate their lost parts.
Explanation:
General Characteristics of Phylum Porifera
Porifera are all aquatic, mostly marine except one family Spongillidae which lives in freshwater.
They are sessile and sedentary and grow like plants.
The body shape is vase or cylinder-like, asymmetrical or radially symmetrical.
Characteristics of coelentrata
All coelenterates are aquatic, mostly marine. The bodyform is radially symmetrical, diploblastic and does not have a coelom. The body has a single opening, the hypostome, surrounded by sensory tentacles equipped with either nematocysts or colloblasts to capture mostly planktonic prey.
