These are one of the largest land tortoises although the Galapagos tortoise may be larger. Large size may be due to the lack of predation and isolation over many thousands of years. The male’s carapace length may measure four feet (1.22 m) and they may weigh up to 550 pounds (250 kg). The female’s carapace may measure three feet (91 cm) and weigh 350 pounds (159 kg). The males have a concave plastron. They are dark gray to black in color with a highly domed, thick carapace. They have long necks, which helps with food gathering." My special opinion was lucky one in the world because every human being wish to live 100 years , Its not possible. Aldabra can live upto 150 years approximately.
