Eine Notiz über das Vorkommen vonPelagonema obtusicauda, eines freilebenden Nematoden in Bryozoen
Helgoländer wissenschaftliche Meeresuntersuchungen volume 25, pages 170–172 (1973)
Kurzfassung
In Zooiden der marinen BryozoaElectra pilosa (L.) wurden zahlreiche Exemplare des freilebenden NematodenPelagonema obtusicauda Filipjev gefunden. Die Nematoden besiedeln offensichtlich die noch jungen Kolonien, in denen sie auch zur Fortpflanzung gelangen. Die Art der Beziehung zwischen den beiden Organismen bedarf noch weiterer Klärung.
Summary
1. This is the first record of occurrence of a free-living nematode,Pelagonema obtusicauda Filipjev, inside the colonies of the bryozoanElectra pilosa (L.).
2. As many as 26 nematodes were recovered from a singleE. pilosa colony.
3. The nematodes attained sexual maturity and many females harboured well-developed eggs.
