In this study, we focus our attention on the DNA sequence variation of the mitochondrial cytochrome oxydase I gene (COI) in the two species of Palinurus. Spiny lobster DNA samples from four Mediterranean localities were analysed to examine the genetic variability at both the intra- and interspecific level. Fur- thermore, the phylogenetic relationships within the family Palinuridae (among the two species of Palinurus, most of the species of Panulirus and all the species of Jasus) are examined. Introduction molecular data for P. elephas and P. mauritanicus refer to the analysis of the nuclear 28S rDNA with In the Mediterranean Sea, two species of spiny the description of species-specific markers but they lobsters are commonly found, both belonging to do not refer to intraspecific nucleotide variability the genus Palinurus Weber, 1795: Palinurus elephas (Cannas et al., 2001).
