Reproductive biology of the crab Munida subrugosa (Decapoda: Anomura: Galatheidae) in the Beagle Channel, Argentina
Munida subrugosawas sampled monthly from November 1997 to November 1999 in the Beagle Channel by means of an epibenthic trawl. The reproductive cycle started in May, re£ected by the occurrence of ovigerous females. Maximum size of oocytes, maximum value of gonadosomatic index in females (16.8 gmmcarapace length [CL]71) and males (1.6 gmmCL71), and the proportion ( 70%) of ovigerous females with...

the hermit crab fauna of the larak island was investigated, which revealed seven species representing five genera and two families. the family diogenidae represents six species namely areopaguristes perspicax (nobili, 1906), clibanarius signatus heller, 1861, dardanus lagopodes (forskål, 1775), d. tinctor (forskål, 1775), d. avarus heller, 1865, d. tirmiziae siddiqui & mclaughlin, 2003, while t...
متن کاملLow richness of hermit crabs community (Crustacea: Decapoda: Paguroidea) and high dominance of Clibanarius signatus in the intertidal zones of Larak Island, Persian Gulf, Iran
Abstract Hermit crabs community in the intertidal zones of Larak Island were investigated through a seasonal sampling at five stations using random quadrate sampling method. Overall, seven species were identified and Clibanarius signatus was the dominant species, which showed high dominance over other species. Using Bray-Curtis cluster analysis for comparing seasonal abundance showed that exce...
متن کاملSpermatophore transfer in the hermit crab Clibanarius vittatus (Crustacea, Anomura, Diogenidae).
Although mating has been described in several hermit crab species, the mechanics of spermatophore transfer have not previously been demonstrated. Evidence from pleopod and gonopore morphology, video observations, and inseminated females indicates that in Clibanarius vittatus the male applies a spermatophoric mass directly onto the female via the gonopores rather than with modified pleopods 1-2 ...
متن کاملFunctional morphology of the reproductive system of Galathea intermedia (Decapoda: Anomura).
Spermatophore formation in Galathea intermedia begins in the proximal part of the vas deferens. The contents subsequently form a spermatophoric ribbon, the so-called "secondary spermatophore," in its distal part. A strongly muscular ductus ejaculatorius is present in the coxa of the fifth pereiopod which builds up pressure for the extrusion of the spermatophoric ribbon. After extrusion, the rib...
