Abstract

The Greenland shark (Somniosus microcephalus) has recently been identified as the world’s longest-living vertebrate animal, which raises conservational concern in light of recently high bycatch. We report the complete mitochondrial genome of S. microcephalus to be 16,730 bp and composed by 13 protein-coding genes, two rRNA genes, 22 tRNA genes, and a control region. The overall nucleotide composition was 30.8% A, 29.9% T, 14.5% G, and 24.9% C, with a total of 39.4% GC content. Phylogenetic analysis confirmed the position of S. microcephalus in the traditional tree of sharks. The availability of the S. microcephalus mitogenome will contribute to further conservational genetic studies of a unique species, listed as ‘data deficient’ on the Norwegian Red List and ‘near threatened’ on the IUCN Red list.
