Camels can survive up to 15 days without water. One of the reasons that they can survive that long is because of their humps. They store fat in their humps (not water) and can use this to help them go longer without water.

It's the fat stored in the body that makes them survive without water for around 40 days while wobbling through the desert.
How Long Can Snails Sleep? Certain land snails can sleep for up to three years in hibernation or estivation. Yes, it's true!
Tardigrades can live years without food. These are their adaptations to extreme climatic conditions in their habitat for survival. Animals like Emperor penguin, Tardigrade do not eat food in extreme climatic conditions and undergoes a dormant stage.
Lithobates catesbeianus is an animal that cannot sleep.
Adapting to water scarcity
Studies have shown that Namibia's desert elephants have a remarkably straitened water intake. Female adult elephants and infants need water every three days; males can go up to five days without water.
In a study published Monday in the Proceedings of the National Academy of Sciences , researchers have now identified the first animal that doesn't use oxygen to breathe: Henneguya salminicola, an 8-millimeter white parasite that infects the flesh of Chinook salmon.
Snakes can generally last around two months without food, however, wild snakes can go without fresh water for months or even weeks. Snakes in captivity shouldn't be restricted water intake for longer than a week.
In the case of the elephant, in fact, it's impossible. Unlike most mammals, the bones in elephant legs are all pointed downwards, which means they don't have the "spring" required to push off the ground.
Regenerating flatworms
This apparently limitless regeneration also applies to aging and damaged tissue, allowing the worms to cheat death indefinitely, according to a study at the University of Nottingham.
Headless roaches are capable of living for weeks. To understand why cockroaches—and many other insects—can survive decapitation, it helps to understand why humans cannot, explains physiologist and biochemist Joseph Kunkel at the University of Massachusetts Amherst, who studies cockroach development.
Tardigrades are tiny, cute and virtually indestructible. The microscopic animals are able to survive in a pot of boiling water, at the bottom of a deep-sea trench or even in the cold, dark vacuum of space.
Kangaroos are grass eaters that live in grasslands that can be very dry with little rainfall. They may be able to go several months without water because they are capable of getting water from the food they eat.
As well as getting water through osmosis, saltwater fish need to purposefully drink water in order to get enough into their systems. Where their freshwater counterparts direct all of the water that comes into their mouths out through their gills, saltwater fish direct some into their digestive tract.
“A horse can live for almost a month without food, but within a mere 48 hours without water a horse can begin to show signs of colic and can quickly develop an impaction, lethargy, and life-threatening sequelae. A horse can only survive about five days without water,” shares Peter Huntington, B.V. Sc., M.A.C.V.
In general, it is likely that a person could survive between 1 and 2 months without food. As many different factors influence the length of time that the body can last without food, this period will vary among individuals.
Dogs need food and water to survive. However, if they are otherwise well, they can survive for around 5 days without food, as long as they are drinking. It's true that dogs have survived for much longer periods without food, but there is a great risk of irreversible damage to their organs and tissues, or death.
Snakes cannot live without oxygen, and in the human gastrointestinal tract would suffocate within a matter of minutes.
Scorpions are organisms which can hold their breath for up to even 6 days. Scorpions are called arachnids, which are members of the animal kingdom's arachnid class. Their modified lungs, which are known as book lungs, also allow them to hold their breath for long.
One species of salamander lacks lungs, so it breathes by absorbing oxygen through its skin and the roof of its mouth. The diving bell spider is able to breathe oxygen underwater by keeping air bubbles attached to its body with tiny, hydrophobic hairs.
The longest ever recorded dive by a whale was made by a Cuvier's beaked whale. It lasted 222 minutes and broke the record for diving mammals. Other whales can also hold their breath for a very long time. A sperm whale can spend around 90 minutes hunting underwater before it has to come back to the surface to breathe.
1. The land mammal who consumes the most water per pound of bodyweight is the cow. A single cow used for her milk on an industrial feed lot can consume up to 100 gallons of water a day during hot summer months, and that adds up.
Elephants are afraid of bees. Let that sink in for a second. The largest animal on land is so terrified of a tiny insect that it will flap its ears, stir up dust and make noises when it hears the buzz of a beehive. Of course a bee's stinger can't penetrate the thick hide of an elephant.
Elephants can sleep both lying down and standing up. Research has shown that elephants in the wild are more likely to sleep standing up, saving them the energy and time it would take to pick themselves up off the ground.
