## Abstract The present review seeks to demonstrate the presence of an inherent biological tendency for the modification of form in cladoceran setae. We present a comparative description of the setal equipment of the cladoceran antenna I, antenna II, maxilla I, maxilla II, each thoracic limb, the c

Abstract
Diversity of the carapace valve structure in the Anomopoda (Crustacea: Branchiopoda) is described. We found that transformations of shape, modifications of the surface and valve margins, and thickening or thinning of the valves, take place independently in different families, sometimes resulting in a convergent similarity. The limits of morphological diversity in these features determine the range of adaptive radiation in general form of the group. (Β© 2009 WILEYβVCH Verlag GmbH & Co. KGaA, Weinheim)
