Trochus pyramis Born is of gonophores.The male reproductive system is mainly composed of the spermaries and spermaductus, instead of mating and others glands.
Homosporous ferns produce sporophytes by intra gametophytic selfing, inter gametophytic mating, or apogamy.Gametangium ontogeny, genetic load, and ploidy affect the mating system of each species.
Moreover: we also have the necessary explosion-proof electrically operated rapes, decoders, flexure nemas, connecting boxes and so on mating with the black-light night-vision camera.
The results showed that a mixed mating system was possibly the main heterogamy of this species, and its endangerment was caused by over-exploitation and habitat loss.
