The complete mitochondrial genome of Cyphocaris challengeri (Amphipoda: Cyphocarididae)

Abstract

The amphipod Cyphocaris challengeri is a globally distributed, highly abundant species of zooplankton. Here, we report the complete mitochondrial genome of C. challengeri obtained using the Illumina sequencing platform from a specimen collected from Puget Sound, Washington. The mitogenome is a circular DNA molecule with a size of 14,338 bp and 26.7% GC content, with 13 protein-encoding genes, 2 rRNAs, and 22 tRNAs annotated. A maximum likelihood phylogenetic analysis including C. challengeri and all other available mitogenomes from Amphipoda places our mitogenome firmly within the Lysianassoidea superfamily, as expected. The newly described mitochondrial genome of C. challengeri fills a gap in valuable reference data for detecting this organism using molecular methods such as environmental DNA.
