Abstract
The film presents the reproductive biology of two enchytraeid species (Enchytraeus albidus, E. crypticus) and different details of the internal organisation. Apart from food uptake and peristaltic movement the records give an account of copulation, shedding of the cocoon and hatching of the young in particular.
