La tartaruga greca a due teste Janus, del museo di storia naturale di Ginevra, compie oggi 25 anni. Si tratta della più vecchia tartaruga bicefala conosciuta al mondo. L'animale ha la particolarità di avere anche due cuori, due paia di polmoni e due stomaci.
Angelica Bourgoin è uno dei guardiani che si occupa di Janus
In natura, l'aspettativa di vita di Janus sarebbe stata estremamente breve: non potendo ritrarre le due teste sarebbe stata vittima del primo predatore, ha dichiarato oggi il direttore del museo Arnaud Maeder.
Anche in cattività, è straordinario che Janus abbia raggiunto una tale età, sottolinea Maeder. Richiede molte attenzioni: due guardiani si alternano giorno dopo giorno per fargli il bagno, dargli da mangiare e fargli fare esercizio. Secondo chi se ne prende cura ogni testa ha il suo gusto e il suo appetito.
Nato il 3 settembre 1997 al Museo di Ginevra, Janus è ormai una celebrità fra gli specialisti proprio a causa della sua eccezionale longevità.
