Adult tortoises can survive a year or more without access to water. [8] During the summer and dry seasons, they rely on the water contained within cactus fruits and mesquite grass. To maintain sufficient water, they reabsorb water in their bladders, and move to humid burrows in the morning to prevent water loss by evaporation. [25]
Tortoises acquire most of their water from dew and sap in vegetation (particularly the Opuntia cactus), which enables them to survive for more than six months without drinking. They can endure up to a year when deprived of all food and water, [ 103 ] surviving by breaking down their body fat to produce water as a byproduct.
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 ...
Snapping turtles can go for months without breathing in the cold winter months where they may be trapped under pond ice. ... very few snapping turtles survive to their adulthood. Life Cycle of the ...
Can sea turtles survive if they are too cold? Faherty said about 60% of the rescued stranded turtles survive. Last year more than 900 sea turtle strandings were reported.
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 Giant tortoises originally made their way to islands from the mainland via oceanic dispersal.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]

[90] During copulation, the male turtle aligns his tail with the female's so he can insert his penis into her cloaca. [91] Some female turtles can store sperm from multiple males and their egg clutches can have multiple sires ...
