Unlike the females, the males have asymmetrical, highly modified fifth legs, which act as a complex grasping organ. The vestigial mandibular endopod, deeply incised mandibular gnathobasis with pointed cusps, reduced number of setae on the first maxillae, and spinous setae of the second maxillae and maxillipeds suggest a predaceous lifestyle. Adult females' length ranges from 1.29-1.46 mm. The adult males' length ranges from 1.15-1.23 mm. Morphological characteristics of the mouthparts indicate a predaceous lifestyle.
Life stages unknown.
Based on the structure of the male fifth legs, Enantiosis is thought to closely resemble the Ridgewayiidae. Though due to the lack of female fifth legs in the Enantiosis, it is suggested that in fact, they are not closely related. Barr, D. 1984. Please email us your comments and questions .
