WHAT DOES PLANULA MEAN IN GERMAN?
planula
The Planula or Planulalarve is a larval form of the Nesseltiere. It forms by gastrulation of the blastula, is two-layered and ciliated. The mouth is usually closed immediately after formation. The planula feeds on plankton or yolk. Flagellation is not uniform in all cases; in the larvae of crustan anemones it is confined to a longitudinal strip. The planula continues to rotate and, after a planktonic stage of a few days to several weeks, fixes its aboral pole on a firm foundation and forms a bonding disk. Then the metamorphosis to the polyp, with the formation of the mouth, if not already present, and the tentacle. In the case of the hydrozoae and the cylindrical roses, the tentacles are formed during the plankton phase. The larvae of Actinula and Arachnactis thus produced are, first of all, free-swimming polyps, and are later transferred to life on the seabed. In medusa-like hydrozoa without generation change, the planula deposits on its mouth and the edge of the flattened region becomes a medusa bell.
