What type of symmetry do ctenophores have?

Step-by-step solution

Ctenophores, commonly known as sea walnuts or comb jellies are exclusively marine, radially symmetrical, diploblastic organisms with tissue level of organisation.. Ctenophores are exclusively marine organisms that have radially symmetrical body structure. Ctenophores have eight external rows of ciliated comb plates which help them in locomotion.Digestion is both extracellular and intracellular. Bioluminescence (the property of a living organism to emit light) is well-marked in ctenophores. Sexes are not separate. R
