Spermatophore 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 کاملSpermatophore consumption in a cephalopod.
An individual's gametes can represent a nourishing food source for a manipulative mate. Here, we provide evidence of ejaculate and sperm consumption in a cephalopod. Through labelling male spermatophores with (14)C radiolabel, we found that female squid, Sepiadarium austrinum, consumed the spermatophores of their partners and directed the nutrients received into both somatic maintenance and egg...
متن کاملSpermatophore Formation in the White Shrimps Penaeus Setiferus and P. Vannamei
The medial and distal vasa deferentia and terminal ampullae of Penaeus setiferus and P. vannamei were studied by light and electron microscopy to assess their roles in spermatophore formation. The ascending medial vas deferens of each species consisted of 2 parallel epitheliumlined ducts, referred to as the spermatophoric and accessory ducts, with the accessory duct fitting into a groove along ...
متن کاملAuto-spermatophore extrusion in male crickets.
The reproductive cycle of the male cricket consists of the mating stage and the sexually refractory stage. The latter is further divided into the first refractory stage (RS1) from spermatophore extrusion in copulation to spermatophore preparation after copulation, and the second refractory stage (RS2) from spermatophore preparation to recommencement of a calling song. RS2 is time-fixed and unaf...
متن کاملSpermatophore Transfer and Ejection in the Beetle
Spennatophore transfer in the beetle Pseudoxychila tarsa/i.s occurred in a-isociation with one of the four movements of the body and aedeagus that males performed during copulation. Some copulations did not result in spermatophore transfer, and females ejected some of the spermatophores they received. This suggests females may be capable of exerting cryptic female choice. Data on spermatophore ...
