DNA barcoding reveals cryptic diversity in marine hydroids (Cnidaria, Hydrozoa) from coastal and deep-sea environments
Fifty-six sequences of the mitochondrial 16S RNA gene were generated for hydroids, belonging to six nominal families - Eudendriidae, Lafoeidae, Haleciidae, Sertulariidae, Plumulariidae and Aglaopheniidae - collected from bathyal environments of the Gulf of Cadiz (22 haplotypes), Greenland (1 haploty...
