Complete mitochondrial genome of Antarctic krill Euphausia superba (Eucarida: Euphausiacea)

Abstract

Antarctic krill Euphausia superba is a very important species in Antarctic ecosystem. The mitochondrial genome of E. superba was completed with 16,591 bp in length, gene arrangement and order was the same as previous studies. The overall A + T content is 68.91% and the control region A + T content is 78.17%. Alignment with other two partial mitochondrial genome revealed that ND2 region possessed many unusual variation sites. The phylogenetic tree showed that E. superba clustered with other two species of Euphausiacea. This study filled in the gap of the krill mitogenome and suggested putative markers for population study.
