Plánula
Sign in to saveA planula is the free-swimming, flattened, ciliated, bilaterally symmetric larval form of various cnidarian species and some species of Ctenophores, which are not closely related to cnidarians. Some groups of Nemerteans also produce larvae that are very similar to the planula, which are called planuliform larva. In a few cnidarian clades, like Aplanulata and the parasitic Myxozoa, the planula larval stage has been lost.

La larva plánula es propia de la mayoría de los cnidarios; algunos grupos de nemertinos producen larvas muy similares a la plánula. Es una larva ciliada, aplanada, con simetría bilateral y que nada libremente. El clado Planulozoa se ha propuesto sobre la base de la hipótesis de que los bilaterales quizá representen una derivación pedomórfica de una larva plánula ancestral.
