Cytogenetic studies in some species of Scorpaeniformes (Teleostei: Percomorpha).
Cytogenetic studies were performed in four species of two scorpaeniform teleost families: Scorpaenidae and Triglidae. The karyotypes of Trigla lucerna, Trigloporus lastoviza (Triglidae), Scorpaena porcus and S. notata (Scorpaenidae) were analysed using various banding methods and in situ hybridization with a telomeric probe. In the two Scorpaena species, modest morphological divergence corresponded to considerable karyotype reorganization, while in the two Triglidae substantial phenotypical divergence corresponded to limited chromosomal changes. These data stress the need for a taxonomical re-evaluation of these teleosts based on characters independent of morphology.
