#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.
Mayflies only live for 24 hours and hold the record for the shortest living life cycle on earth. This might be good news to anyone who hates bugs, but not all bugs have short lifespans. There are a few bugs that can live for years, even decades.
Although there are several species among many groups of insects that exist for only a few days as adults, the shortest adult reproductive life belongs to the female of the mayfly Dolania americana (Ephemeroptera) which lives for less than five minutes after its final molt.
LUNA MOTH Also known as the giant silk moth, the beautiful, lime-green luna moth lives around only a week after they emerge from the cocoon as an adult. Males will fly long distances to mate, if necessary, and females will die once they lay their eggs.
Bees' short-term memory is quite weak, despite their unique abilities. A comparable study on chimpanzees found that bees had the worst memory, with a recall duration of just 2.5 seconds.
The spider lifespan can vary as much as the spider life cycle. Most spiders live about two years, but some have been known to live up to 20 years when in captivity. Female spiders tend to live longer than male spiders. Many male spiders reach maturity within two years and die after mating.
Because it lives on Earth only for 24 hours or less. Mayfly is an aquatic insect belonging to the same group of insects as dragonflies. Mayflies spend most of their lives in water as nymphs. They live as aquatic larvae for about a year or maybe more and as soon as they reproduce, they die.
Mayflies spend most of their lives in the water as nymphs and then emerge as adults for only a short while. Adults will live only a day or so, but the aquatic larvae lives for about a year. Their status is unknown. There are more than 600 species of mayfly in the United States and 3,000 worldwide.
Solution: Giraffes sleep only for an average of just 30 minutes per day as they are having the shortest sleep requirement in mammals.
Wild elephants average just 2 hours of sleep a night, making them the lightest-known snoozers of any mammal. Previous studies have looked at such habits in captive elephants, which sleep for 3 to 7 hours a day. But with more dangers and pressure to find food, wild animals tend to sleep less.
Ephemeral mayflies
We often hear that mayflies, like the whiteflies of the Susquehanna River, have the shortest lifespan of any animal on Earth, just 24 hours for many species.
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.
The Longest-lived Insect: The queen of termites, known to live for 50 years. Some scientists believe that they live for 100 years. The Oldest Fossil Butterfly or Moth: A Lepidoptera fossil found in England is estimated to be 190 million years old.
200 years: Bowhead Whale lifespan - the longest living mammal.
Each species of cockroach has their own estimated lifespan but on average, cockroaches live for about one year. Factors such as food supply, habitat and climate affect lifespan. American cockroaches can live for about one year while German cockroaches are estimated to live for about 100 days.

These insects are the shortest living animals on the planet, as the adult lifespan of a fly from this species is only 24 hours.
What is a tardigrade? 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. Around 1,300 species of tardigrades are found worldwide.
Spiders do not sleep in the same way that humans do, but like us, they do have daily cycles of activity and rest. Spiders can't close their eyes because they don't have eyelids but they reduce their activity levels and lower their metabolic rate to conserve energy.
It is likely to lack key features such as 'distress', 'sadness', and other states that require the synthesis of emotion, memory and cognition. In other words, insects are unlikely to feel pain as we understand it.
Some spiders have life spans of less than a year, while others may live for up to twenty years. However, spiders face many dangers that reduce their chances of reaching a ripe old age. Spiders and their eggs and young are food for many animals.
