Abstract
The haploid DNA content and karyotypes of eight species of Blennius are studied. Six species had 2n=48, two had 2n=46.
The karyotypes of these species have been compared with those of related species of the genus and it was suggested that pericentric inversions played an important role in the evolution of their karyotypes. No sex chromosomes were morphologically identifiable in these gonochorist species. The data are discussed in connection with possible lines of evolution within the genus.
