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.
Scorpion — 1 year. Scorpions eat one-third of their body weight in just one meal. This alone helps them to slow down their metabolism and handle their nutrition, making it possible to last for a year without food.
Crocodiles can live for 2 years without food or water.
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.
But snakes take this to the extreme. They can range from eating a meal nearly every day to only once in a whole year! It depends a lot on the species of snake, its age and size, and the size of its last meal.
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.
In mammals, the Virginia opossum (commonly known simply as possums) is perhaps the best known example of defensive thanatosis. "Playing possum" is an idiomatic phrase which means "pretending to be dead". It comes from a characteristic of the Virginia opossum, which is famous for pretending to be dead when threatened.
#1: Mayfly — The Shortest Lifespan of Any Known Animal
These insects are the shortest living animals on the planet, as the adult lifespan of a fly from this species is only 24 hours.
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.
Answer: Kangaroo rat
The tiny kangaroo rat located in the south-western deserts of the United States does not drink water for its whole lifespan. Kangaroo rats represent an integral part of desert life.
Snails need moisture to survive; so if the weather is not cooperating, they can actually sleep up to three years. It has been reported that depending on geography, snails can shift into hibernation (which occurs in the winter), or estivation (also known as 'summer sleep'), helping to escape warm climates.
Scorpion: 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.
Or so we thought. 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.
Animals that don't need sleep (bullfrogs and dolphins) Animals that don't need rebound sleep after using up all their energy (bees) Animals that show harmful side effects from sleep deprivation (humans)
Brown-throated three-toed sloth
The brown-throated three-toed sloth (Bradypus variegatus) sleeps a lot! In fact, this sloth sleeps for about 14 to 16 a hours a day. Unlike nocturnal animals that have made the list, the brown-throated three-toed sloth sleeps during the day and night.
With no food and no water, the maximum time the body can survive is thought to be about one week . With water only, but no food, survival time may extend up to 2 to 3 months. Over time, a severely restricted food intake can reduce the lifespan.
Ocean Quahogs (Clams)
Ocean quahogs live in the Atlantic and can live more than 400 years old. At 507 years of age, Ming the clam broke the Guinness World Record as the oldest animal in the world.
Why the ostrich is the only living animal with four kneecaps.
The new research shows that dolphins have the longest memory yet known in any species other than people. Elephants and chimpanzees are thought to have similar abilities, but they haven't yet been tested, said study author Jason Bruck, an animal behaviorist at the University of Chicago.
Cockroaches are infamous for their tenacity, and are often cited as the most likely survivors of a nuclear war. Some even claim that they can live without their heads. It turns out that these armchair exterminators (and their professional brethren) are right. Headless roaches are capable of living for weeks.
Funny Riddle What animal turns about 200 times around its axis after it dies? A roast chicken.
While it has not been proven that non-human animals do, or even can, die by suicide, many animals behave in ways that may seem suicidal. There are anecdotes of animals refusing to eat in periods of grief or stress. Some social insects have been known to defend their colony by sacrificing themselves.
A growing body of scientific evidence supports the idea that nonhuman animals are aware of death, can experience grief and will sometimes mourn for or ritualize their dead.
