These tortoises can weigh as much as 417 kg (919 lb) and can grow to be 1.3 m (4 ft 3 in) long. Giant tortoises originally made their way to islands from the mainland via oceanic dispersal. Tortoises are aided in such dispersal by their ability to float with their heads up and to survive for up to six months without food or fresh water. [3]
Turtles can live long lives. The oldest living turtle and land animal is said to be a Seychelles giant tortoise named Jonathan, who turned 187 in 2019. [101] A Galápagos tortoise named Harriet was collected by Charles Darwin in 1835; it died in 2006, having lived for at least 176 years. Most wild turtles do not reach that age.
Much of the tortoise's water intake comes from moisture in the grasses and wildflowers they consume in the spring. A large urinary bladder can store over 40% of the tortoise's body weight in water, urea, uric acid, and nitrogenous wastes. During very dry times, they may give off waste as a white paste rather than a watery urine. During periods ...

In the northern part of their range common snapping turtles do not breathe for more than six months because ice covers their hibernating site. These turtles can get oxygen by pushing their head out of the mud and allowing gas exchange to take place through the membranes of their mouth and throat. This is known as extrapulmonary respiration.

Young Russian tortoises should be soaked 1-2x/weekly in lukewarm water no deeper than their elbows to keep hydrated. Tortoises typically empty their bowels in water to hide their scent; this is an instinct, and it also helps keep their enclosure cleaner. [16] Russian tortoises can live up to 50 years, and require annual hibernation. [citation ...
On Long Island, bird foster operator Linda McGay takes in parrots from emergency situations, often after their owner passes away without making a plan. “We handle the deaths," McGay said. McGay ...
Despite being unable to swim, tortoises are able to survive long periods adrift at sea because they can survive months without food or fresh water. Tortoises have been known to survive oceanic dispersals of more than 740 km. [26] Once on islands tortoises faced few predators or competitors and could grow to large sizes and become the dominant ...
