脊索动物分为三个亚门：脊椎动物门、被膜动物门和头索动物门。在系统发育上，鲸脊索动物，通常被称为文昌鱼或文昌鱼，构成了脊椎动物和被膜动物的姐妹群。蓝鳍金枪鱼是小型的底栖海洋滤食性动物，其大约36个已描述的物种被分为三个属：鳃口鱼属、上棘鱼属和棘鱼属。由于它们的系统发育位置和它们典型的脊索动物形态学和基因组结构，lancarpus是理解脊索动物进化历史的关键模型。因此，几代科学家都在研究兰桂鱼，最早的成年解剖学和发育形态学描述可以追溯到世纪。今天，几种不同的文昌鱼物种被用作实验室模型，主要用于发育，分子和基因组研究。然而，令人惊讶的是，科学界尚未采用通用的分期系统和用于发育柳叶刀的明确命名法。在这项工作中，我们的特点是欧洲文昌鱼（Branchiostoma lanceolatum）使用共聚焦显微镜的发展，并编制了一个精简的发展分期系统，从受精到幼虫的生活，包括一个明确的阶段命名。通过追踪在不同温度下饲养的欧洲文昌鱼的生长曲线，我们能够证明我们的分期系统允许将任何发育时间轻松转换为特定的阶段名称。此外，还对欧洲文昌鱼（B. lanceolatum）、佛罗里达文昌鱼（Branchiostoma floridae）、两种亚洲文昌鱼（Branchiostoma belcheri和Branchiostoma japonicum）和巴哈马文昌鱼（Amphalonlucayanum）证明了我们的分期系统可以容易地应用于其他文昌鱼物种。虽然对发展中的B. lanceolatum，与其他lancelet物种的比较，因此强烈建议分期和命名适用于所有现存的lancelet。我们的结论是，这种描述的胚胎和幼虫的发展将是非常有用的科学界，它应该被采纳为新的标准，定义和命名发展中的lancelae。更一般地说，我们预计，这项工作将有利于未来的研究比较不同的脊索动物谱系的代表。
Chordates are divided into three subphyla: Vertebrata, Tunicata, and Cephalochordata. Phylogenetically, the Cephalochordata, more commonly known as lancelets or amphioxus, constitute the sister group of Vertebrata and Tunicata. Lancelets are small, benthic, marine filter feeders, and their roughly three dozen described species are divided into three genera: Branchiostoma, Epigonichthys, and Asymmetron. Due to their phylogenetic position and their stereotypical chordate morphology and genome architecture, lancelets are key models for understanding the evolutionary history of chordates. Lancelets have thus been studied by generations of scientists, with the first descriptions of adult anatomy and developmental morphology dating back to the 19th century. Today, several different lancelet species are used as laboratory models, predominantly for developmental, molecular and genomic studies. Surprisingly, however, a universal staging system and an unambiguous nomenclature for developing lancelets have not yet been adopted by the scientific community. In this work, we characterized the development of the European lancelet (Branchiostoma lanceolatum) using confocal microscopy and compiled a streamlined developmental staging system, from fertilization through larval life, including an unambiguous stage nomenclature. By tracing growth curves of the European lancelet reared at different temperatures, we were able to show that our staging system permitted an easy conversion of any developmental time into a specific stage name. Furthermore, comparisons of embryos and larvae from the European lancelet (B. lanceolatum), the Florida lancelet (Branchiostoma floridae), two Asian lancelets (Branchiostoma belcheri and Branchiostoma japonicum), and the Bahamas lancelet (Asymmetron lucayanum) demonstrated that our staging system could readily be applied to other lancelet species. Although the detailed staging description was carried out on developing B. lanceolatum, the comparisons with other lancelet species thus strongly suggested that both staging and nomenclature are applicable to all extant lancelets. We conclude that this description of embryonic and larval development will be of great use for the scientific community and that it should be adopted as the new standard for defining and naming developing lancelets. More generally, we anticipate that this work will facilitate future studies comparing representatives from different chordate lineages.
