Aspects of the life cycle of marine nematodes

Abstract

1. Life cycles of approximately one month are recorded for laboratory maintained cultures of chromadorid, monhysterid and oncholaimid nematodes. 2. Amphimictic and parthenogenetic reproduction occurs in the species investigated. Reproduction in Monhystera parelegantula is by parthenogenesis. 3. The chromadorid Chromadorina epidemos and the oncholaimid Viscosia macramphida are able to reproduce by either amphimixis or parthenogenesis. 4. Acanthonchus cobbi, Chromadora macrolaimoides and Euchromadora gaulica are amphimitically reproducing species. © 1966 Biologischen Anstalt Helgoland.
