     Considering all the ecological data, there seems to be an evolution in the associations of ostracods throughout time.

     This study has also shown that the fifth limb is most probably of thoracic origin and hence ostracods have only one pair of maxillae.

   • 2012, Ivana Karanovic, Recent Freshwater Ostracods of the World: Crustacea, Ostracoda, Podocopida, page 64,

     A number of parasites and epibionts have been reported from freshwater ostracods, including cestodes, protozoans, helminthes, peritrichs, and acanthocephalans (Griffits and Evans 1994).
