自从在佛罗里达州发现活着的鲤鱼 Rivulus marmoratus Poey 以来（Harrington 和 Rivas，1958 年），在长期被忽视的博物馆标本的基础上，它作为有效物种复活（Rivas，1945 年）之后，它就充满了惊喜。作者在野外采集的所有标本都具有该属雌性的典型外观，但已被证明是雌雄同体（Harrington，1961），排出自体受精卵，亲本孵化时间从几分钟到21天不等，然后是更长的亲本孵化（Harrington，1963）。每个野生捕获的祖先与其单亲实验室后代之间以及后者之间的组织移植均产生自体移植反应，表明它们属于一个克隆，而一些野生捕获的斑鳢个体之间以及一些与其他个体的单亲后代之间的移植物则产生了自体移植反应。
T E cyprinodontid fish Rivulus marmoratus Poey has been full of surprises since it was found alive in Florida (Harrington and Rivas, 1958), following its revival as a valid species, on the basis of long overlooked museum specimens (Rivas, 1945). All specimens taken in the wild by the writer have had the external appearance typical of the females of this genus but have proved to be hermaphrodites (Harrington, 1961), emitting self-fertilized eggs with intraparental incubations ranging from a few minutes to 21 days, followed by much longer extraparental incubations (Harrington, 1963). Tissue grafts between each wild-caught progenitor and its uniparental laboratory descendants and among the latter so tested gave the autograft reaction, showing that they belong to one clone, while grafts between some wild-caught individuals of R. marmoratus and between the uniparental descendants of some and those of others
