  author={Sarah Hayer and Stephanie K{\"o}hnk and Susann Boretius and Dirk Brandis},
  journal={Journal of Morphology},
The reproductive system of the female Ethusa mascarone was studied with a combination of histological and MRI‐techniques. The study reveals a completely new type of eubrachyuran seminal receptacle. This receptacle consists of two largely separate chambers that engage with each other in a manner similar to shaking hands. One chamber facing the medial axis is lined by cuticle while the second chamber consists of a thick holocrine epithelium. Both chambers are connected by two openings of a unique…

Functional morphology of the female reproductive system of a crab with highly extensible seminal receptacles and extreme sperm storage capacity

The functional morphology of the female reproductive system of the purple stone crab Danielethus crenulatus is studied and the anatomical structure of the vulva and vagina suggest active female control over copula, which is compatible with rival sperm displacement and last sperm precedence.



Morphology and function of the female reproductive system of Ebalia tumefacta (Decapoda, Brachyura, Leucosiidae)

The morphology and function of the female reproductive organs of Ebalia tumefacta were investigated using histological methods and revealed a new orientation of seminal receptacle compartments in Eubrachyuran crabs.


It is hypothesize that muscles attached to the female genital ducts could allow females to selectively permit male ejaculates access to the seminal receptacle, or direct the ejaculate into the bursa, a feature rarely found in other brachyurans.

Functional anatomy of the female reproductive systems of two spider crabs (Decapoda, Majoidea)

The functional anatomy of the female reproductive systems of the spider crabs Leurocyclus tuberculosus and Libinia spinosa is studied, comparing them with those of other Majoidea to determine whether the morphology of the seminal receptacles is related to different mating strategies or behaviors.

Copulatory system of the spider crab Libinia spinosa (Crustacea: Brachyura: Majoidea)

Morphological characteristics shown by the gonopods of mature males develop synchronously with the acquisition of physiological maturity, not with morphometrical maturity, while the mature holding systems and vulvae of females are developed synchronous with physiological and morphometric maturity.

Functional morphology of the copulatory system of box crabs with long second gonopods (Calappidae, Eubrachyura, Decapoda, Crustacea)

This work investigates male and female copulatory organs in Calappula saussurei and Calappa pelii, two species of box crabs with second gonopods which are longer than the first pair, and proposes that long second Gonopods deliver male mating products directly into the dorsal chamber.

Morphology of the female reproductive system of European pea crabs (Crustacea, Decapoda, Brachyura, Pinnotheridae)

It is notable that structure and function of spermathecal secretion are more complex in pinnotherids, and probably more efficient, than in other brachyuran crabs.

Structure and Function of the Reproductive System of the Symbiotic Spider Crab Inachus Phalangium (Decapoda: Majidae): Observations on Sperm Transfer, Sperm Storage, and Spawning

The structure and function of the reproductive tracts of the spider crab Inachus phalangium were investigated, focusing on sperm transfer, sperm storage in the seminal receptacles, and spawning.

Structure of the Female Reproductive Tract in the Dungeness Crab (Cancer magister) and Implications for the Mating System.

Anatomical and behavioral aspects of reproduction in female Dungeness crab, Cancer magister, were investigated and a novel organ that often contains sperm, the bursa, is reported for the first time for a brachyuran crab.
