We investigated the ultrastructure of spermatozoa and spermatophores of 19 palaeotropical freshwater crab species [12 species of the Gecarcinucidae, 6 of the Potamidae (Potamiscinae), and 1 species of the Potamonautidae (Deckeniinae: Hydrothelphusini)]. The investigated Potamiscinae have densely packed coenospermic spermatophores with the exception of Thaiphusa sirikit and Johora singaporensis that exhibit cleistospermia. In contrast, in the Gecarcinucidae the spermatozoa are loosely embedded… 
Comparative morphology of the spermatophores and spermatozoa of three Amazon freshwater crabs (Decapoda, Brachyura, Trichodactylidae)
TLDR
The ultrastructure of spermatophores and spermatozoa of Dilocarcinus pagei, Zilchiopsis oronensis and Valdivia serrata are described and compared to reinforce the hypothesis that the trichodactylids derived later as an independent lineage of freshwater crabs.
Evolution of sperm morphology in potamid freshwater crabs (Crustacea: Brachyura: Potamoidea)
TLDR
The results suggest that the use of brachyuran acrosome morphology for phylogenetic inference at the family level is strongly affected by small sample size, and by convergent character evolution.
Fine structure of the spermatozoon in three species of Cambaridae (Arthropoda: Crustacea: Decapoda) Cambarus robustus, Orconectes propinquus and Orconectes rusticus: a comparative biometrical study
TLDR
A combination of morphological features and biometrical data of spermatozoa can help distinguishing different species of the freshwater crayfish.
Comparative ultrastructure of the spermatozoa of three crayfish species: Austropotamobius torrentium, Pacifastacus leniusculus, and Astacus astacus (Decapoda: Astacidae)
TLDR
Differences in the dimensions of the acrosome within the studied species may be useful to help distinguish the different crayfish species.
Male internal reproductive structures of european pea crabs (Crustacea, Decapoda, Brachyura, Pinnotheridae): Vas deferens morphology and spermatozoal ultrastructure
TLDR
The male internal reproductive structures and the ultrastructure of spermatozoa of Pinnotheres pisum and Nepinnotheres pinnotheres are investigated by histological methods and transmission electron microscopy, finding the latter being an exceptional location for reproductive structures among male brachyurans.
Unistellate spermatozoa of decapods: comparative evaluation and evolution of the morphology
TLDR
Comparative evaluation of spermatozoal morphology and current phylogenetic evidences corroborates the hypothesis that the spermatozoon spike of carideans and dendrobranchiates is the result of convergent evolution.
Ultrastructure and histochemistry of the male reproductive system of the genus Callinectes Stimpson, 1860 (Brachyura: Portunidae)
TLDR
Overall, the reproductive pattern of Callinectes is similar to other species that produce sperm plugs, and the traits identified here are common to all Portunidae species studied so far.
Is cleistospermy and coenospermy related to sperm transfer? A comparative study of the male reproductive system of Pachygrapsus transversus and Pachygrapsus gracilis (Brachyura: Grapsidae)
TLDR
The differences in spermatophore structure and the characteristics of seminal fluid seem to indicate physiological differences related to sperm transfer.

Ultrastructure and relationships of spermatozoa of the freshwater crabs Potamon fluviatile and Potamon ibericum (Crustacea, Brachyura, Potamidae)
TLDR
The spermatozoa of Potamon fluviatile and P. ibericum are virtually indistinguishable and do not support separate subgeneric rank (Potamon and Pontipotamon), and their assignment to the Heterotremata is not in doubt.
Ultrastructure of the spermatozoon of Potamonautes perlatus sidneyii (Heterotremata, Brachyura, Crustacea)
TLDR
Peculiarities of Potamonautes relative to other heterotremes (and paguroid anomurans) are the indistinct substructure of the acrosomal ray zone; absence of a recognizable inner acrosome zone differentiated from this, and reduction of the thickened ring, the latter trend being taken to completion in grapsid Thoracotremata.
ULTRASTRUCTURE OF THE SPERM AND SPERMATOPHORES OF THE GOLDEN CRAB GERYON FENNERI AND A CLOSELY RELATED SPECIES, THE RED CRAB G. QUINQUEDENS, FROM THE EASTERN GULF OF MEXICO
The sperm of species of Geryon are typical of brachyurans in having a complex acrosome, a membranous lamellar complex, uncondensed chromatin in the nucleus, and nuclear arms or spikes of varying
Studies on The Comparative Ultrastructure of Crab Spermatozoa (Crustacea,Decapoda,Reptantia,Brachyura)
TLDR
Comparative sperm morphology of three species of crab, Portunus trituberculatus, Eriocheir sinensis and Sinopotamon yangtsekiense, has been investigated with light and electron microscopes, revealing that several differences exist the crab spermatozoa in three species.
Reproductive Processes Revealed by Spermatophore Dehiscence Experiments and by Histology, Ultrastructure, and Histochemistry of the Female Reproductive System in the Snow Crab Chionoecetes Opilio (O. Fabricius)
TLDR
Histological, histochemical, ultrastructural, and microbiological techniques were used to elucidate the structure and function of the female reproductive system in the snow crab Chionoecetes opilio, with emphasis on roles and interactions of secretions, bacteria, spermatophore storage, and dehiscence.
Comparative Spermatozoal Ultrastructure of the Three Dromiacean Families Exemplified by Homolodromia Kai (Homolodromiidae), Sphaerodromia Lamellata (Dromiidae), and Dynomene Tanensis (Dynomenidae) (Podotremata: Brachyura)
TLDR
Spermatologically Sphaerodromia lamellata appears closer to the dynomenid Dynomene tanensis than it is to the mutually paraphyletic Dromidiopsis edwardsi and Stimdromia lateralis.
Histochemical characteristics of spermatophore layers of Scylla serrata (Forskal) (Decapoda: Portunidae)
TLDR
It is suggested that, in S. serrata, the dehiscence of spermatophore may be caused by imbibing of low molecular weight substances by the sperm mass, and the mechanism of sperm release is recorded and discussed.
Phylogeny of the Brachyura with particular reference to the Podotremata: evidence from a review of spermatozoal ultrastructure (Crustacea, Decapoda)
TLDR
Spermatozoal data give majids the most basal position in the Heterotremata whereas for the combined data Neodorippe (a shell carrier) appears the least modified member of the heterotreme-thoracotreme assemblage.
