Comparative phylomitogenomic analyses provide insights into adaptation and carcinization in Anomura.

ABSTRACT: Anomura is a morphologically and ecologically diverse infraorder of decapod crustaceans, yet its evolutionary and phylogenetic patterns remain underexplored using mitochondrial genome-based approaches, particularly regarding adaptive evolution across diverse environments. Here, we present a comprehensive phylogenomic analysis of 42 anomuran mitochondrial genomes, including three newly sequenced species: two intertidal Hapalogastrinae (Hapalogaster dentata and Oedignathus inermis) and one deep-sea pagurid (Pagurus rathbuni). The arrangement of protein-coding genes was identical to that reported in previously studied Lithodidae and Paguridae species; however, several tRNA genes exhibited translocations. Moreover, more than half of the 22 tRNA genes were predicted to adop
