Los planulozoos (Planulozoa) es un hipotético clado que propone incluir tanto a cnidarios (anemonas y medusas) como a los bilaterales (deuterostomos, protostomos y acoelomorpha) exceptuando a los ctenóforos, poriferos y placozoos.[1]​[2]​[3]​ Este clado se ha planteado sobre la base de la hipótesis de que los bilaterales quizá representen una derivación pedomórfica de una larva plánula de los cnidarios.[1]​[4]​[5]​
