potamoidea meaning in Chinese
溪蟹总科
Examples
- The phylogenetic analysis of these two nonmarine crabs together with intertidal , supratidal and swimming crabs based on portions of mitochondrial 16s rdna sequences suggested that grapsioidea , ocypodoidea , potamoidea and portunoidea arose from a common marine ancestor , and the estimated divergence time are similar . the freshwater crab phylogeny suggested that the genus sinopotamon and the genus potamonautes arose from a common ancestor and the estimated divergence time is about 36 - 44 mya
基于线粒体16srdna部分序列，对这2个类型的非海洋蟹类与潮间带蟹类、海洋蟹类之间的系统发生分析提示，方蟹总科( grapsioidea ) 、沙蟹总科( ocypodioidea ) 、溪蟹总科( potamoidea )和梭子蟹总科( portunoidea )的蟹类起源于一个共同的海洋蟹类祖先，它们彼此之间的歧异时间基本一致。
