They are sometimes classified with the COELENTERATES but more usually given the status of a phylum. WebCtenophora Ctenophores are planktonic organisms that are jelly-like in form but, unlike true jellies, they propel themselves by beating rows of compound cilia in waves. Their movement is therefore very gentle and gradual. The compound cilia occur in comb rows, five …
