Aldabrachelys gigantea hololissa
Giant tortoises are among the longest-lived animals on the planet. Some individual Aldabra giant tortoises are thought to be over 200 years of age, but this is difficult to verify because they tend to outlive their human observers. Adwaita was reputedly one of four brought by British seamen from the Seychelles Islands as gifts to Robert Clive of the British East India Company in the 18th century, and came to Calcutta Zoo in 1875. At his death in March 2006 at the Kolkata (formerly Calcutta) Zoo in India, Adwaita is reputed to have reached the longest ever measured life span of 255 years (birth year 1750). Today, Jonathan, a -year-old, Saint Helena-dwelling Seychelles giant tortoise, is thought to be the oldest living terrestrial animal on Earth since the 2006 death of Harriet; a 176 year old Galapagos giant tortoise who lived at Australia Zoo. Coming in second to Jonathan is Esmeralda, at years old. Esmeralda is an Aldabra giant tortoise that lives in the Galapagos Islands.
Yellow-footed tortoise
This yellow-footed tortoise eats many kinds of foliage. They are too slow to capture any fast animals. In the wild, their diets consist of grasses, fallen fruit, carrion, plants, bones, mushrooms, excrement, and slow-moving invertebrates such as snails, worms, and others they are able to capture. In captivity, they are fed oranges, apples, melons, endive, collard greens, dandelions, plantain, ribwort, clover, shredded carrots, insects, worms, cuttlebone, tortoise vitamins, edible flowers, and alfalfa pellets. Each yellow-footed tortoise in the wild reaches the age of maturity at about 8–10 years. The fecundity of a female generally depends on her size; the bigger they are, the more eggs they can produce. On average, a female will create about six to 16 eggs per year, although some female individuals may not reproduce each year. The eggs have brittle shells and are elongated to spherical, about 3–6 cm in diameter. The egg size will increase with the body size of the tortoise. The young are self-sufficient from birth. The yellow-footed tortoise can live around 50–60 years.
