Mitochondrial genome of the critically Endangered silver boa (Chilabothrus argentum; Squamata: Boidae).

We present the complete mitochondrial genome of Chilabothrus argentum, which is 17,345 bp in length, has 22 transfer ribonucleic acids (tRNAs), 2 ribosomal subunits (rRNAs), 13 protein-coding genes, an origin of the light-strand replication (OL), and two control regions (CR1, CR2). A maximum likelihood phylogenetic estimate using nine other snake mitochondrial genomes yields agreement with previous investigations into the evolutionary relationships of snakes.
