Résumé

Une étude de chromosomes des poissons polyptères africains,Polypterus palmas etCalamoichthys calabricus révèle un nombre diploïde de 36. Ce caryotype a été comparé à celui du Dipneustes, du Holostéens et du Chondrostéens. Il ressort de cette analyse que les Polyptères occupent une situation intermédiaire entre celles des Actinopterygii et des Dipnoi, ce qui légitime le point de vue selon lequel ils doivent être placées dans une sousclasse distincte, les Branchiopterygii.
