The use of spermatozoal characters in elucidating animal phylogeny (spermiocladistics) has
been successfully applied in the decapod crustaceans. Most of the studies investigating …

In the debate over phylogenetic relationships within the Decapoda that has raged for more
than a century, the Anomura has been the source of many “confl icts”, including …

Study of the reproductive strategy of crayfish species is of great importance in the current
astacological world. Crayfish are among the largest freshwater invertebrates, and as …

Reflecting the wide variety of ideas and hypotheses concerning decapod phylogeny, the
world's leading decapodologists assemble their knowledge in this volume for the sole …

This study reports about the spermatozoal ultrastructure of three species of astacid crayfish,
ie, the stone crayfish Austropotamobius torrentium, signal crayfish Pacifastacus leniusculus …

Ultrastructure of spermatozoa of three crayfish genera including Orconectes limosus
(Rafinesque, 1817), Procambarus clarkii (Girard, 1852), and Astacus leptodactylus …

The spermatophore morphology of the hermit crab Isocheles sawayai from southwestern
Atlantic (Brazil) is described. The spermatophores show similarities with those described for …

We describe the male reproductive system of the intertidal hermit crab Calcinus tibicen, with
emphasis on the sexual apparatus, spermatophore, and spermatozoa. The crabs were …

The previously published ultrastructure of Aegla spermatozoa contributed to the
phylogenetics of this unique taxon. The present study describes the spermatozoa of two …
