The chromosomes of the living coelacanth and their remarkable similarity to those of one of the most ancient frogs.
The karyotype of the coelacanth is reported for the first time. Latimeria chalumnae has a 48-chromosome karyotype that contains metacentric, subtelocentric, and telocentric chromosomes as well as microchromosomes. This karyotype is unlike those found in lung-fishes but is very similar to the 46-chromosome karyotype of one of the ancient frogs, Ascaphus truei.
