Molecular identification of the arrowhead dogfish Deania profundorum (Centrophoridae) from the northern waters of the Iberian peninsula

Abstract

This is the first molecular identification of the Arrowhead dogfish Deania profundorum based on the mitochondrial cytochrome oxidase c subunit I (COI) ever made. It is based on four specimens caught in the Cantabrian Sea (north of Spain) during a monitoring survey in the summer of 2009. Three specimens of Deania calcea were also sampled as comparative material. The sequences obtained were in concordance with the identification of the Deania species. The two Deania species shared no COI haplotypes and showed a genetic distance of 3.6% (23 fixed differences out of 652 bp), which is within the range of congeneric species.
