基本解釋

Morphologies of glochidium and juvenile mussel were studied during parasitic metamorphosis development of Anodonta woodiana pacifica.
摘要對(duì)圓背角無齒蚌的鉤介幼蟲寄生變態(tài)及稚貝發(fā)育過程進(jìn)行了形態(tài)學(xué)觀察和比較。
After a period of growth, newly shells which were similar to adults came out near side of glochidium shells, which were degenerating as shell bottom gradually.
稚貝經(jīng)過一段時(shí)間的生長，從幼蟲殼內(nèi)側(cè)長出一對(duì)新殼，形態(tài)逐漸趨向于成貝，而幼蟲殼則逐漸退化為殼頂。
Mature glochidium was only capable of switching by shells, while the newly metamorphosed juveniles were near identical to glochidium in size and shape except for the ability of movement by foot.
剛脫落的稚貝外部形態(tài)與幼蟲相似，但已經(jīng)可以依靠斧足進(jìn)行爬行，并逐漸開始濾食；
