glochidium การใช้

• It is established worldwide despite having, like all unionid mussels, an obligatory parasitic stage ( glochidium ), which must encyst on host fish.
• After fertilization, the eggs develop into a larval stage called a glochidium ( plural glochidia ), which temporarily parasitizes fish, attaching themselves to the fish's fins or gills.
• Like other fresh water mussels in the family Unionidae, the Ouachita creekshell has a complex life history involving a larval stage known as a glochidium which attaches itself to the gill, fin or skin of a suitable host fish.
• The "'glochidium "'( plural "'glochidia "') is a microscopic larval stage of some freshwater mussels, aquatic bivalve mollusks in the families Unionidae and Margaritiferidae, the river mussels and European freshwater pearl mussels.
• "' Glochids "'or "'glochidia "'( singular " glochidium " ) are hair-like spines or short prickles, generally barbed, found on the areoles of spines, which do not readily detach and are not generally barbed.
• Cacti often have a particular kind of spine ( as found in areoles of " Opuntia " ) called a "'glochidium "'or "'glochid "'( plural glochidia or glochids ), which is very small and deciduous with numerous retrose barbs along its length.
• Some other common trees and large shrub species of subtropical forests are " Semecarpus anacardium, Cretaeava unilocularis, Trewia nudiflora, Premna interrupta, Ulmus lancifolia, Ulmus chumlia, Glochidium velutinum, Callicarpa arborea, Toona ciliata, Ficus " spp ., " Mahosama similicifolia, Trevesia palmate, Xylosma longifolium, Boehmeria rugulosa, Scheffera venulosa, Michelia " spp ., " Casearia graveilens, Rhus wallichii, Actinodaphne reticulata, Sapimum insegne, Alnus nepalensis, Ardisia thyrsiflora, Ilex " spp, " Macaranga pustulata, Trichilia cannoroides, Celtis tetranda, Wenlendia puberula, Saurauia nepalensis, Ligustrum confusum, Quercus glauca, Zizyphus incurva, Camellia kissi, Hymenodictyon flaccidum, Maytenus thomsonii, Zanthoxylum armatum, Rhus succednea, Eurya acuminata, Myrsine semiserrata, Slonea tomentosa, Hydrangea asper, Symplocus " spp ., " Cleyrea " spp . and " Quercus lamellose ".
