A new mtDNA control region haplotype from sea lamprey (Petromyzon marinus Linnaeus, 1758: Petromyzontiformes) collected off the Italian Adriatic coast

Given the lack of genetic information about Mediterranean sea lamprey, taking advantage of recent capture of two individuals in the western Adriatic Sea, molecular analysis of a partial sequence of the mitochondrial DNA control region has been performed on two Mediterranean specimens for the first time. A new haplotype is reported for this species. Furthermore, the finding of both juvenile and adult individuals suggests the presence of suitable rivers for reproduction in the Adriatic region.
