Abstract

The Mediterranean spiny lobsters, the common spiny lobster Palinurus elephas (Fabricius, 1758) and the pink spiny lobster P. mauritanicus Gruvel, 1911, are important target species for commercial fisheries. 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. Furthermore, 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
