Chromadorea Rhabditida Rhabditia Panagrolaimidae
Panagrolaiminae
Panagrolaimus Thorne, 1937
Identification of Panagrolaimus species from morphological characters is challenging due to variability of morphometric cherecters. Molecular methods should improve theirclassification and identification.
Photographs indicating characteristics of the genus are P. margarethe
Bacterial feeders (Yeates et al., 1993; Moens and Vincx, 1997).
Members of the genus Panagrolaimus are bacterial-feeding nematodes Some members of this genus can survive extreme desiccation by entering into anhydrobiosis.
Panagrolaimus app. may be used as models for the study of the evolution of reproductive systems as they exhibit three reproductive modes: gonochoristic, hermaphroditic and parthenogenetic. This is a unique characteristic that has not yet been reported in other nematode species (F�lix et al.,, 2000).
