摘要

The Chamidae are widely distributed in the tropical to temperate seas, with >70 known species. Currently, their classification relies mainly on traditional morphological methods and identification primarily on small fragment genes, such as COI. The intrafamily phylogenetic relationships are ambiguous, lacking support from reliable molecular data. In this study, the mitochondrial genomes of eight species of Chamidae were sequenced for the first time and then annotated. Their structures and compositional characteristics were analyzed. The mitochondrial gene order in this family differed significantly. Concurrently, the evolutionary position and phylogenetic relationship among Chamidae species were explored, and the Veneroida phylogenetic tree was recreated. Maximum Likelihood and Bayesian Inference analyses supported the monophyly of Chamidae. Additionally, the divergence time within Chamidae was estimated based on mitochondrial DNA sequences, with the most ancient divergence estimated to occur during the early Cretaceous period, 128 MYA. This phylogeny is significant for understanding the diversity and taxonomic status of Chamidae.
