Adult females of 14 of 25 species of the family calanidae were found to be dimorphic with respect to the number of aesthetases on the first antenna. The trithek morph, in which most antennal segments bear a complement of one aesthetasc and two setae, appears to be the typical female phenotype. The quadrithek morph is less common and, as in males, odd-numbered segments 2b, 3, 5, 7 and 9 carry.

In this review we consider sexual dimorphism in copepods, cladocerans, and rotifers. All three groups may be common components of freshwater and sometimes estuarine zooplankton communities, but only the copepods are generally found in marine zooplankton communities. To varying degrees, these three groups exhibit important differences between the sexes in size and in other secondary sexual.
