Hi.

here is your answer.

Ctenophora , commonly known as sea walnut or comb jellies are exclusively marine, radially symmetrical, diploblastic organism with tissue level of organisations.

The body bears eight external rows of cilliated comb plates, which is both extra cellular and intracellular.

Bioluminescence is well marked in ctenophora.

sexes are not separate. Reproduction takes place only by sexual means. Fertilisation is external with indirect development.


hope it helps you ☺
