We studied the functional morphology of the female reproductive system of the purple stone
crab Danielethus crenulatus. The most remarkable feature is the relative storage capacity …

One of the most remarkable features of the reproductive systems of eubrachyuran crabs is
the presence of specialized organs for sperm storage, the seminal receptacles. Descriptions …

The origins and evolution of sperm storage in Brachyura are enigmatic: sperm is either
stored in seminal receptacles, accessible via the vulvae on the sixth thoracic sternite, or in …

Reproductive anatomy, including sperm storage structures and sperm transfer, is an
important feature used to analyze phylogenetic relationships among taxa. We describe the …

The external and internal architecture of crab seminal receptacles are closely associated
with mating behavior, sperm transfer, and storage patterns, and ultimately reproductive …

Variation in female sperm storage is explained, in part, by the amount of sperm transferred at
mating. Laboratory mating experiments were conducted on Eurypanopeus depressus and …

Female reproductive systems are important characters for understanding the evolution of
Brachyura and resolving its phylogenetic relationships. We herein investigate a podotreme …

The male reproductive system of Amazon freshwater crabs Sylviocarcinus pictus and
Dilocarcinus pagei were described and compared in terms of anatomy and histochemistry In …

In the brachyuran crab Metopograpsus messor mating occurs only among" hard"(intermolt)
individuals. Our present light and electron microscopic studies reveal that the …

We used an histological approach to describe the female sperm storage organ (seminal
receptacle) of the freshwater crab Limnopilos naiyanetri. The crescent-shaped sclerotized …
