Question

Comment on the symmetry of coelenterata.

Answer 1

Explanation:

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.

Answer 2

They  mostly have radical symmetry. Rarely bilateral symmetry.
