The ocean quahog is a fist-size clam that can live to be 500 years or older. Some researchers believe the sturdy quahog's secret to a long life is its ability to protect its proteins from damage.
Estimates of sponge longevity vary quite a bit, but are often in the thousands of years. One study in the journal Aging Research Reviews notes a deep-sea sponge from the species Monorhaphis chuni lived to be 11,000 years old. Yes, a sponge is an animal—and it has a remarkable life-span.
Greenland Shark
It is the longest living vertebrate on earth. They owe their longevity in life as they grow very slowly. In fact, they grow about 1cm every year and mature after they are 100 years old. They reach sexual maturity after they are 150 years old.
There are a number of marine species that outlive humans, and the mammal species that holds the record for longevity is the bowhead whale, which can live for 200 years - or more.
Turritopsis dohrnii
The jellyfish Turritopsis dohrnii has no brain and heart and is considered the only immortal creature on Earth; it lives in tropical waters.
Some corals can live for up to 5,000 years, making them the longest living animals on Earth. Scientific studies of elkhorn coral (Acropora palmata) in the Caribbean and off the coast of Florida show that coral genotypes can survive longer than expected.
How Long Do Snakes Live? Snakes reach sexual maturity within two to four years, depending on the species and living conditions. In perfect conditions, adult snakes live anywhere from 20 to 30 years, with natural predators and the encroachment of humans severely limiting the number of years most snakes live.
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.
Bluey, an Australian cattle dog, entered the Guinness Book of World Records by living to the ripe old age of 29 years and 5 months, setting the record for oldest dog ever.
The First Animals
Sponges were among the earliest animals. While chemical compounds from sponges are preserved in rocks as old as 700 million years, molecular evidence points to sponges developing even earlier.
The increased longevity of humans is, in part, attributable to environmental changes; improved food, water, and hygiene; reduced impact of infectious disease; and improved medical care at all ages.
Bowhead whale
The bowhead, thought to be the longest-living mammal, is estimated to live beyond 200 years. Researchers sequenced the genome of a bowhead whale in 2015 and identified genes related to DNA repair, cancer and aging that could be responsible for the animal's long life.
Greenland sharks live for between 300 and 500 years and are the longest-living vertebrate. They take life very slowly, moving at an average of 0.76 mph. They grow about a cm every year, and females may not reach sexual maturity until they are 100 to 150 years old – that's one long childhood!
Methuselah, a bristlecone pine in the White Mountains of California, stands at the ripe old age of about 5,000, making it the oldest known non-cloned living organism on Earth.
Some scientists believe that within the next few decades, it could be possible for humans to live 1,000 years or more. Normally, as time passes, our cells undergo changes: Our DNA mutates, cells stop dividing, and harmful junk—by-products of cellular activity—builds up. All these processes together cause us to age.
Which animal in the world can live for 1000000000 years without growing old? The jellyfish Turritopsis dohrnii has no brain and heart and is considered the only immortal creature on Earth; it lives in tropical waters.
The greatest age reliably recorded for a horse is 62 years for Old Billy (foaled 1760), bred by Edward Robinson of Woolston, Lancashire, UK.
The oldest cat who ever lived, Crème Puff, reached the age of 38 years and three days. They died on August 6, 2005. The former oldest living dog, Pebbles, died on October 3, five months before the toy fox terrier's 23rd birthday.
Creme Puff (August 3, 1967 – August 6, 2005) was a domestic cat, owned by Jake Perry of Austin, Texas, US. She was the oldest cat ever recorded, according to the 2010 edition of Guinness World Records, when she died aged 38 years and 3 days. Austin, Texas, U.S.
Lobsters and crabs have teeth— in their stomachs. These are used to crush its food, but they also have a strange secondary function in ghost crabs: making a noise that wards off predators.
Lithobates catesbeianus is an animal that cannot sleep.
Most species of mayfly, also known as Canadian Soldiers in the US, live for about a day. However, the adult life of a female Dolania americana lasts a matter of minutes. Talk about living for the moment! It's remarkable the species has survived, as the female must mate and lay her eggs before her short time is up.
Wadjet, also spelled Wadjit, also called Buto, Uto, or Edjo, cobra goddess of ancient Egypt. Depicted as a cobra twined around a papyrus stem, she was the tutelary goddess of Lower Egypt.
While studies showed that snakes originated in the Paleocene Epoch between 65-56 million years ago, the most recent discovery dates the oldest snakes back to 167 million years ago. The remains of the oldest recorded snake, aged 167 million years ago, were found in Southern England.
Abstract. Although average human life expectancy is rising, the maximum lifespan is not increasing. Leading demographers claim that human lifespan is fixed at a natural limit around 122 years.
