Abstract
We determined the complete mitochondrial genome sequence of nurse shark Ginglymostoma cirratum. The circular DNA of 16692 bp comprises 13 protein-coding genes, 22 transfer RNAs, 2 ribosomal RNAs, a non-coding control region and a non-coding origin of light strand replication with typical gene order of vertebrates. The nurse shark formed a well-supported clade that included whale shark Rhincodon typus and zebra shark Stegostoma fasciatum within the Orectolobiformes in a phylogenetic tree constructed with other published mitochondrial genomes of sharks.
