16对海底海洋无脊椎动物的幼体来说，从浮游生物到海底生物的定居是一个关键的过渡。“绝望的幼虫”概念描述了幼虫随着年龄的增长接受次优定居生境的趋势。我们量化了19只东方牡蛎Crassostrea virginica的浮游幼虫的游泳行为，以确定20种定居行为，如向下游泳和留在底部，是否随着21岁的增加而增加，以及这些个体发育变化是否在暴露于次优22
16 For larvae of benthic marine invertebrate species, settlement from planktonic to benthic 17 life is a critical transition. The “desperate larva” concept describes the tendency of larvae to 18 accept suboptimal settlement habitats as they age. We quantified swimming behavior in 19 planktotrophic larvae of the eastern oyster, Crassostrea virginica, to determine whether 20 settlement behaviors, such as swimming downward and remaining on the bottom, increased with 21 age and whether these ontogenetic changes were more apparent in larvae exposed to suboptimal 22
