โœฆ Synopsis

The oostegites of amphipods attached to peraeopods 2-5 are of two main typesbroad with relatively short marginal setae and narrow with long marginal setae. Broad oostegites are found in other peracarids and are considered the primitive type. Amphipods with broad oostegites tend to have smaller eggs than those with narrow oostegites. It is concluded that following the evolution of the major amphipod groups, the oostegites were modified as egg sizes have changed as part of the reproductive strategies of the species within these groups.
