planula

The planula then settle to the bottom, and develop into polyps.

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

After 3 days the egg develops in a planula at this stage movement is only done by ciliary action.

The planula then flattens into a pedal disk with 4-6 lobes.

The planula is a small larva covered with cilia.

Once attached to a substrate, a planula quickly develops into one feeding polyp.

After fertilization a primitive free-swimming larval form, called the planula, develops.

Fertilized eggs develop into small ciliated larvae called planula.

With Cubozoans, the planula settles onto a suitable surface, and develops into a polyp.

Six days following fertilization, a cone-shaped and benthic, larval planula develops.

These fertilized eggs remain attached to her oral arms, and there they grow into flat bean-shaped planula.

Thus, a planula is aboral.

The coral planula, commonly called seedlings, are grown up in tanks in an indoor facility.

Release of eggs or planula usually occurs at night, and is sometimes in phase with the lunar cycle (three to six days after a full moon).

The released eggs are fertilized, and the resulting zygote develops quickly into a multicellular planula.

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

The fertilised egg develops into a planula, which settles after fifteen to twenty days and grows into a new individual.

The resultant zygote develops into a free swimming planula larva before attaching itself to a suitable site.

The gametes fuse during fertilization to form a microscopic larva called a planula, typically pink and elliptical in shape.

This idea suggests that metazoa are derived from a planula; that is, the tadpole-like larva of certain cnidaria.

A planula is the free-swimming, flattened, ciliated, bilaterally symmetric larval form of various cnidarian species.

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 planula of Clytia gregaria settle on a variety of substrates, on both horizontal and vertical surfaces.

Following fertilisation, the zygote becomes a microscopic larva called a planula, which, upon swimming to suitable substrate, will anchor and establish a new colony.
