Complete mitochondrial genome of the spiny rock crab Thalamita crenata (rüppell, 1830) (Crustacea: Decapoda: Portunidae) from China coast and its phylogeny

Abstract

To understand the evolution of the swimming crab Thalamita crenata, the complete mitochondrial genome of T. crenata from China was sequenced and analyzed. The circular mitogenome sequence was 15,787 bp in length, made up of 13 protein-coding genes, 22 transfer RNA genes, two ribosomal RNA genes and a control region. The overall mitogenome composition was 34.40% for A, 11.55% for G, 35.31% for T, and 18.74% for C, respectively, with a high A + T content of 69.71%. Phylogenetic analysis showed that T. crenata was closest to the genus Charybdis.
