Examples of planula
planula
The fertilized egg develops into a planula, which settles and grows into a single polyp.

The planula is an active swimmer, and it moves primarily in the direction of the apical tuft.

Similarities with cnidarian planula may indicate an ancestral developmental stage for metazoans.

Subsequent development produces a tiny larva, known as a planula.

The positively buoyant gametes float towards the surface where fertilization produces planula larvae.

The released eggs are fertilized, and the resulting zygote develops quickly into a multicellular planula.
From the en.wikipedia.org
The similarities observed in Xenacoelomorpha hatchlings, cnidarian planula larvae and poriferan parenchyma larvae support this view.
From the nature.com
The gametes fuse during fertilization to form a microscopic larva called a planula, typically pink and elliptical in shape.
From the en.wikipedia.org
In cnidarians, this stage is called the planula, and either develops directly into the adult animals or forms new adult individuals through a process of budding.

- The flat ciliated free-swimming larva of hydrozoan coelenterates
- A planula is the free-swimming, flattened, ciliated, bilaterally symmetric larval form of various cnidarian species. The planula forms from the fertilized egg of a medusa, as the case in scyphozoans and some hydrozoans, or from a polyp, as in the case of anthozoans. ...

- The larval stage of a coral
