planula larva stage

Planulalarvenstadium {n}biol.

• The Hydroidolina follows a biphasic life cycle, which alternates in occurrence as planula larva, asexual colonial sessile polyps and free-swimming sexual medusa, not all of which may be present in the one life cycle of the Hydroidolina.
• The egg hatches in the digestive system of the intermediate host, producing a planula larva.
• DNA comparisons suggest that placozoans are related to Cnidaria, derived from planula larva (as seen in some Cnidaria).
• Under this life cycle, a planula larva develops into the deposits of the ocean floor and begins asexually reproducing as a polyp.
• Like most corals, "Goniopora columna" reproduce asexually. They usually feed on plankton. Mature gametes are spawned through the mouth. The zygote develops into a planktonic planula larva.

• Like most corals, "Tubastraea faulkneri" reproduce asexually. They are hermaphrodites. Mature gametes are spawned through the mouth. The zygote develops into a planktonic planula larva.
• After fertilisation, the zygote develops into a planula larva which is brooded by the female inside the bell.
• After fertilisation, the planula larva forms part of the plankton before settling on the seabed, undergoing metamorphosis and developing into a juvenile sea anemone.
• Each develops into a planula larva which settles and develops into a juvenile sea anemone.
• This fusion results in free swimming planula larva that eventually sinks to the bottom or finds a hard surface to attach to.

• The resultant zygote develops into a free swimming planula larva before attaching itself to a suitable site.
• The zygote develops into a planula larva which swims by means of cilia and forms part of the plankton for a while before settling on the seabed and metamorphosing into a juvenile polyp.
• Unlike other cnidarians, anemones (and other anthozoans) entirely lack the free-swimming medusal stage of their life cycle; the polyp produces eggs and sperm, and the fertilized egg develops into a planula larva, which develops directly into another polyp.
