The averagelifespan of animals varies greatly from a few days to hundreds of years. The Antarctic sponge CinachyraAntarctica has lived for 1550 years, the ArcticaIslandica clam for more than 400 years. The longest-living vertebrate is the Aldabra giant tortoise (Aldabrachelysgigantea), which can live for more than 200 years. The longest-living mammal is the bowhead whale (Balaenamysticetus) (up to 200 years). Another long-live mammal is an elephant, who lives up to 70 years. People in more economically developed countries normally live for 80 years, but there is a group of people over the age of 100 years. We can also find enormous lifespan differences among birds. The golden eagle (Aquila chrysaetos) lives up to 80 years, the large parrots Ara up to 70 years old, while the small songbirds live 5-10 years.
