Trochophore, tseem hu ua trochosphere, me me, translucent, dawb-ua luam dej larva yam ntxwv ntawm marine annelids thiab feem ntau pawg ntawm mollusks. Trochophores yog spherical los yog pear-puab thiab yog girdled los ntawm ib lub nplhaib ntawm cilia (feeb hairlike lug), lub prototroch, uas ua rau lawv ua luam dej
Tus trochophore txav hauv dej li cas?
A trochophore (/ˈtroʊkəˌfɔːr, ˈtrɒ-, -koʊ-/; kuj spelled trocophore) yog ib hom kev ua luam dej dawb planktonic marine larva nrog ntau pawg cilia. Los ntawm txav lawv cov cilia sai sai, ib qho dej eddy yog tsim. Ua li no lawv tswj cov kev taw qhia ntawm lawv lub zog.
