Crocodiles can live for 2 years without food or water.
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.
You will be surprised to know that crocodiles, as one of the oldest reptiles of the planet can go for a few months without food, and in extreme cases, they can go up to three years without food. They save energy by moving slow and at times by being motionless too.
The emperor penguin is one of the few warm-blooded animals to go for weeks without eating. Due to the harsh winters they face on the Antarctic ice, they have adapted to survive without food for up to two months while traveling to open water or broken ice in which to hunt.
How long can a Lion go without eating? Lions can go without food for more than a week and then tear into prey, eating up to 50kg of meat at a time - that's almost a quarter of the animal's body weight.
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.
Adult wolves can survive for days and even weeks without food if they have to. Growing pups, however, require regular nourishment in order to be strong enough to travel and hunt with the adults by the autumn of their first year.
The kangaroo rat's kidneys are so efficient that it never needs to drink water. It gets all of its liquid from the plants, roots, and seeds it eats. Nonetheless, it is sufficient to keep the kangaroo rat alive.
Tardigrades are among the most resilient animals known, with individual species able to survive extreme conditions – such as exposure to extreme temperatures, extreme pressures (both high and low), air deprivation, radiation, dehydration, and starvation – that would quickly kill most other known forms of life.
Kangaroo rats, according to scientists, are the only animals that can exist without water. According to the findings, they do not have any water in their bodies for any of their digestive functions. Kangaroo rats can survive in deserts without ever drinking.
The 'immortal' jellyfish, Turritopsis dohrnii
To date, there's only one species that has been called 'biologically immortal': the jellyfish Turritopsis dohrnii. These small, transparent animals hang out in oceans around the world and can turn back time by reverting to an earlier stage of their life cycle.
However, unlike other mammals, adult dolphins and whales are able to go without sleep for a month.
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.
Another specimen had a recorded lifespan of 374 years. The tubeworm Escarpia laminata that lives in deep sea cold seeps regularly reaches the age of between 100 and 200 years, with some individuals determined to be more than 300 years old. It is possible some may live for over 1000 years.
The Sign Eviota, Eviota sigillata, a tiny coral reef fish, completes its entire life cycle within an eight week period. This species has the shortest lifespan of any vertebrate.
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.
What kills tardigrades? Research shows that tardigrades can be killed by exposure to hot water for an extended period of time. One study showed that one hour of exposure to water at 82.7 °C (180.9 °F) can kill a tardigrade in its “tun” state, where it goes into suspended animation and becomes hard to destroy.
Platypus
Platypus are solitary animals for most of their lives, although they can sometimes be seen in pairs.
Tardigrades are microscopic eight-legged animals that have been to outer space and would likely survive the apocalypse. Bonus: They look like adorable miniature bears.
Adaptations. The kangaroo rat is almost perfectly adapted to life in the desert. They can survive without ever drinking any water, getting needed moisture from their seed diet.
Jellyfish, starfish, and even corals manage very well without hearts. Starfish do not even have blood, so this explains why no heart is required. Instead, they use small hair-like structures called cilia to push seawater through their bodies and they extract oxygen from the water.
Ants are small, but they can drink a lot of water depending on their body weight. Your typical ant, in an average setting, probably drinks about 7 microliters of water. This is equivalent to 1/5th of a drop of water.
Wolves are notorious for the unique order in which they consume their prey. Shortly after the kill, a wolf will tear open the animal's abdominal cavity and consume the organs. The “prized meat,” which is consumed first, includes the liver, heart, kidneys, spleen, and other vital organs.
Do lions eat everyday? Lions are believed to feed every three or four days, and need on average between 5kg and 7kg of meat a day. But they can go without food for more than a week and then tear into prey, eating up to 50kg of meat at a time – that's almost a quarter of the animal's body weight.
