带有德累森科亚的贻贝类也许是最特化和最成功的异肌双壳类。它们的相似性可能不是系统发育的，如Purchon和Brown（1969）所提出的，而是趋同和采用相似习性的结果（Yonge和坎贝尔，1968）。因此，欧洲的DreissenidDreissena po/ymorpha和亚洲的Mytild Limnoperna forlunei都采用了一种生活方式，包括在淡水沃茨的硬表面定居（Morton 1969 a，出版中）。在这些双壳类中异肌性条件的进化可能来自不同的同肌性祖先，幼足丝被成体保留在幼期（Yonge 1962）。这一过程发生在沿海浅沃茨，一定使现代物种的祖先最初能够在潮间带定居。在这里，贻贝类已经非常成功，并栖息在世界各地的岩石海岸。其他mytil id可以在滨海地区找到，例如，Crenella（Soot-Ryen 1955）;在河口，例如，Xenoslrobus（Wilson 1967）;在淡水沃茨中，例如，Limnoperna（Morton，in press）;甚至作为高度专业化的，例如，Fungiaeava（Goreau等人，1969）。相比之下，Dreissenacea没有经历过这种广泛的适应性辐射，并且仅限于河口，例如，康吉利亚（Wolff 1969）和淡水沃茨，例如，Dreissena（Morton 1969 a）.然而，在它们的影响范围内，这两种双壳类都引起污染生物的问题，例如，Dreissena（Morton 196ge）和Mylilus（Haderlie 1968）。
THE MYTILACEA with the Dreissenacea are perhaps the most specialized and most successful heteromyarian bivalves. Their similarity is probably not phylogenetic, as suggested by Purchon and Brown (1969), but is the result of convergence and the adoption of similar habits (Yonge and Campbell 1968). Thus, the European dreissenid Dreissena po/ymorpha and the Asian mytilid Limnoperna forlunei have both adopted a mode of life involving the colonization of hard surfaces in fresh waters (Morton 1969a in press). The evolution of the heteromyarian condition in these bivalve lines probably proceeded from different isomyarian ancestors, with the neotenous retention of the larval byssus by the adult (Yonge 1962). This process, occurring in shallow coastal waters, must have enabled the ancestors of modern-day species initially to colonize the intertidal zone. Here the Mytilacea have been extremely successful and inhabit rocky shores the world over. Other mytil ids may be found sublittorally, e.g., Crenella (Soot-Ryen 1955); in estuaries, e.g., Xenoslrobus (Wilson 1967); in fresh waters, e.g., Limnoperna (Morton, in press); and even as highly specialized commensals, e.g., Fungiaeava (Goreau et al. 1969). The Dreissenacea by contrast have not undergone this extensive adaptive radiation and are restricted to estuaries, e.g., Congeria (Wolff 1969) and fresh waters, e.g., Dreissena (Morton 1969a). Within their spheres of influence, however, both of these bivalve lines cause problems as fouling organisms, e.g., Dreissena (Morton 196ge) and Mylilus (Haderlie 1968).
