Members of the amphipod suborder Caprellidea exhibit degenerated abdomens and pereopods 3 and 4. Some genera of Podoceridae (Gammaridea, Corophioidea) such as Dulichia also show reduced abdomens and pereopods and thus are generally regarded as a sister group of the Caprellidea. In addition, one of the caprellid families, the Caprogammaridae, exhibits abdominal segments that are similar to those of the podocerids, as well as rudimentary pereopods 3 and 4, which are more consistent with those of… CONTINUE READING
