We present a review of the data on the intervertebral autotomy and regeneration of agamid lizards based on an analysis of information obtained over a 35-year period after the publication of thorough reviews (Arnold, 1984, 1988 and Bellairs, Bryant, 1985). It is supplemented by our own studies of 869 specimens of agamid lizards (Sauria, Agamidae) stored in the herpetological collections of the Zoological Institute of the Russian Academy of Sciences (St. Petersburg, Russia) and the Zoological Museum of the Moscow State University (Moscow, Russia), represented by 31 species of 16 genera. The manifestations of the ability for autotomy and regeneration in phylogenetic lineages within the family-Leiolepidinae, Amphibolurinae, Agaminae, Draconinae-are considered. A comparative morphological analysis of the structure of the caudal vertebrae was carried out using the Computer Microtomography Methods (micro-CT) in the following ecomorphological types of agama: (1) with developed abilities to caudal autotomy and regeneration, (2) with the ability to caudal autotomy but without regeneration and (3) without the ability to autotomy. The phenomenon of intervertebral autotomy (urotomy) in snakes is considered too. Possible ways of evolution of the ability to caudal autotomy as a defense strategy against predators are discussed in the phylogenetic context.
基于对全面综述（阿诺德，1984年、1988年；贝莱尔斯、布赖恩特，1985年）发表后35年间所获信息的分析，我们对鬣蜥的椎间自切与再生数据进行了综述。本文还补充了我们自己对869个鬣蜥标本（蜥蜴目，鬣蜥科）的研究，这些标本保存在俄罗斯科学院动物研究所（俄罗斯圣彼得堡）和莫斯科国立大学动物博物馆（俄罗斯莫斯科）的爬虫类藏品中，涵盖16个属的31个物种。我们考虑了鬣蜥科内系统发育谱系——柔蜥亚科、澳虎亚科、鬣蜥亚科、飞蜥亚科——中自切和再生能力的表现。利用计算机显微断层扫描方法（显微CT），对以下生态形态类型的鬣蜥尾椎结构进行了比较形态学分析：（1）具有发达的尾部自切和再生能力；（2）具有尾部自切能力但无再生能力；（3）无自切能力。文中也讨论了蛇类的椎间自切（尾切）现象。在系统发育背景下，探讨了尾部自切能力作为一种防御捕食者的策略可能的进化方式。
