Sperm ultrastructure of shrimps from the family Penaeidae (Crustacea: Dendrobranchiata) in a phylogenetic context
(2017-07-01)
We describe the sperm ultrastructure of six penaeid species, including at least one member of each tribe (Penaeini, Parapenaeini and Trachypenaeini). Fragments of the vas deferens of the Penaeidae Farfantepenaeus brasiliensis, ...
Ultrastructure of Sorubim lima (Teleostei, Siluriformes, Pimelodidae) spermiogenesis
(2000-10-01)
The spermiogenesis and the spermatozoon ultrastructure of Sorubim lima were studied. Our observations showed that early spermatids are round-shaped cells, have spherical nucleus with diffuse chromatin, small quantity of ...
Comparative sperm ultrastructure of two tegu lizards (genus Salvator) and its relation to sperm competition
(Elsevier Gmbh, 2017-03)
The knowledge of sperm ultrastructure of Squamata provides informative traits for phylogenetic analyses. Furthermore, several sperm ultrastructure traits are important for sperm motility and longevity. Here, we provided a ...

Differences in sperm morphology in foam-nesting leptodactyline frogs (Anura, Leptodactylidae)
(Wiley-Blackwell, 2017-01-01)
Sperm morphology is diverse among vertebrates and is influenced by the reproductive strategies adopted by species. In anurans, sperm morphology is associated with reproductive modes and mating systems. Here, we describe ...
