每个模式物种都需要自己的发育表。Astyanax mexicanus是一种包括有视力的河流种群和失明的洞穴种群的硬骨鱼，在发育和进化生物学领域越来越重要。因此，一个发育分期表是越来越必要的，特别是因为早期发育事件的比较分析被研究人员广泛采用。我们从表层鱼和Pachon洞穴鱼种群中收集了新鲜产卵的胚胎。胚胎在发育的第一天每10-12分钟成像一次，在接下来的几天里频率较低。结果提供了一个说明比较选定的发育阶段，从一个细胞到孵化这两个群体。这两种形态在主要事件上表现出本质上的同步发展，如表观代谢、神经发育、体细胞发生、心脏跳动或孵化。我们还提供了在幼虫发育过程中出现的特殊形态特征的数据，如眼睛大小，卵黄退化，鱼鳔和鳍发育。本文还详细介绍了F1 Pachon洞x表面杂交品种的发展情况。与斑马鱼的发育进行了比较。
Every model species requires its own developmental table. Astyanax mexicanus, a teleost fish comprising both sighted river and blind cave populations, is becoming more and more important in the field of developmental and evolutionary biology. As such, a developmental staging table is increasingly necessary, particularly since comparative analysis of early developmental events is widely employed by researchers. We collected freshly spawned embryos from surface fish and Pachon cavefish populations. Embryos were imaged every 10-12 min during the first day of development, and less frequently in the following days. The results provide an illustrated comparison of selected developmental stages from one cell to hatching of these two populations. The two morphs show an essentially synchronous development regarding major events such as epiboly, neurulation, somitogenesis, heart beating, or hatching. We also present data on particular morphological characters appearing during larval development, such as eye size, yolk regression, swim bladder, and fin development. Some details about the development of F1 Pachon cave x surface hybrids are also given. Comparisons are made with Danio rerio (zebrafish) development.
