The colorful Clownfish lives longer than 20 years in the aquarium. Researchers of the Scuola Normale Superiore in Pisa, Italy, in collaboration with the Leibniz Institute on Aging (FLI) in Jena, Germany, have investigated the genetics behind the longevity of clownfish. By sequencing the genome and comparing the sequences with other species, they were able to show, that the secret of this longevity lies in the mitochondria and lysosomes of the clownfish. Because it is uncomplicated to keep and breed clownfish, they represent an interesting new animal model for research on longevity. The results are now published in the journal BMC Evolutionary Biology.
