The ontogeny of the female reproductive system in the parasitic castrator pea crab Calyptraeotheres garthi: Implications for its mating system
(Wiley-liss, Div John Wiley & Sons Inc, 2018-04)
The knowledge of the mating system of pea crabs is still fragmentary as it remains dubious whether females copulate in the juvenile and free-living ‘hard’ or in the obligatory symbiotic stages (adult stage ‘V’ or intermediate ...
Functional morphology of the male reproductive system in Callichirus major (Crustacea: Decapoda: Axiidea): Evidence of oocytes in the gonad
(Wiley Blackwell Publishing, Inc, 2018-01)
Callichirus major inhabits the intertidal region of marine ecosystems and it is frequently used as live bait for fishing. This study aimed to describe the functional anatomy of the male reproductive system by microscopic ...
Morphology of the male reproductive system of freshwater prawn Macrobrachium carcinus (Decapoda, Caridea): Functional and comparative aspects
(2020-04-01)
Testes and vasa deferentia are parts of the male reproductive system of decapod crustaceans. Both organs show morphological differences among decapod species in terms of anatomical and histological patterns reflecting the ...
Simultaneous activity of male and female gonads in intersex hermit crabs
(Inter-research, 2010-01-01)
