Until June 2007, seventy-eight species of Amphibians' complete sequence of mitochondrial genome were presented in GenBank. The gene numbers in the genomes range from 35 to 41; the 78 mtDNA genomes can be divided into 22 types and further clustered as 3 groups based on the gene number, kind and arrangement. The type 4 is a common type among the class Amphibia and other vertebrate, type 8 is common among the three orders of living Amphibia.

对2007年6月13日以前公布于GenBank上的78种两栖动物的线粒体基因组全序列进行了总结、比较和分析。78种基因组中基因的数量从35~41个不等；根据基因的数量、种类及其排列顺序的差别将其分为22种基因组类型，其进而聚为3组，其中类型4为两栖纲与其它脊椎动物的常见类型，类型8为两栖纲中现生3个目的公有类型。
