The resting eggs of the Ctenopoda (Crustacea: Branchiopoda): a review

The resting eggs of the Ctenopoda have been studied since the second half of the 19th century. By now they are known in 21 species of the group but only in 4 species (Sida crystallina, Diaphanosoma brachyurum, Penilia avirostris and Holopedium gibberum) have they been investigated thoroughly.

Description
Summary:The resting eggs of the Ctenopoda have been studied since the second half of the 19th century. By now they are known in 21 species of the group but only in 4 species (Sida crystallina, Diaphanosoma brachyurum, Penilia avirostris and Holopedium gibberum) have they been investigated thoroughly. Gross and internal structure of eggs are characterized by considerable diversity. In general their structure has much in common with resting eggs of the Anostraca, Notostraca, "Conchostraca" and Onychopoda as well as with that of some other remotely related groups of freshwater invertebrates (Rotifera, Hydra). The taxonomic value of resting eggs is discussed. Probably they play a significant role in determining geographical distribution. Waterfowl are the main agent of their dispersal.
