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.
Florida mouse
Gestation is about 23 or 24 days. The mice dig side burrows off the main burrow of the gopher tortoise, line them with shredded plant material, and use them as nurseries. In eight litters of young conceived in the wild but born in the laboratory, litter size numbers varied from two to four for an average of 3.1 per litter. The young are born in nests in the burrow. Newborn weigh and measure in total length ; tail length ; and hind foot length . Teeth begin appearing on the fourth day, the young are active and agile about the 10th day, and the eyes open about the 16th day. Nursing is virtually non-stop for the first two weeks of life. Weaning occurs at three to four weeks, and the young display adult behavior at this time.
