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.
The ocean quahog is a species of edible clam, a marine bivalve mollusk. 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.
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.
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.
No animal can sleep for 300 years.
The correct answer is that they rest throughout the day. They rest lightly throughout their active months, but when hibernation season comes around, they dive in deep waters to sleep, that is.
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.
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.
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.
Humans' life expectancy (average) is 70-85 years. However, the oldest verified person (Jeanne Clement, 1875-1997) lived up to 122 years. As a person ages, the telomeres (chromosome ends) tend to become shorter in every consecutive cycle of replication. Also, bones start getting weaker by reducing in size and density.
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.
If the limits of human life currently oscillate between 110 and 120 years, with both biological and genetic advances, in the future this could reach 600 or 700 years.
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 record was set in 1939 and still stands, but many Australian Cattle Dogs have tried to beat it by living good long lives of their own.
His name is Jonathan, known as the Seychelles giant tortoise that was delivered to the island of Saint Helena in 1882. It has become the oldest known living land animal. In what feels more like a biblical age, the longest living animal in the world has reached 190 years old.
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.
But the bullfrog, Lithobates catesbeianus show the same reaction in both situations. This indicates that bullfrogs do not sleep. Lithobates catesbeianus is an animal that cannot sleep.
Flatworms, nematodes, and cnidarians (jellyfish, sea anemones, and corals) do not have a circulatory system and thus do not have blood. Their body cavity has no lining or fluid within it.
Bullfrogs… No rest for the Bullfrog. The bullfrog was chosen as an animal that doesn't sleep because when tested for responsiveness by being shocked, it had the same reaction whether awake or resting.
Koalas. Hats off to the (somewhat disputed) king of sleep: the Koala bear. They've been reported to sleep up to 22 hours a day in captivity, over 90% of their lives.
Koala – 22 hours
Found only living in Australia, they mainly live in the eucalyptus trees and spend around 22 hours of their time sleeping (90%).
Spiders usually have eight eyes but few have good eyesight.
Some spiders have median eyes that can detect polarised light and they use this ability to navigate while hunting.
Aquatic animals. Glass sponges found in the East China Sea and Southern Ocean have been estimated to be more than 10,000 years old.
SEA FOREST: Approximately 200,000 years. A sprawling sea grass meadow ten miles long near Spain ranks as the oldest known single organism on Earth, according to geneticists. Posidonia oceanica, known as Neptune's grass, is endemic to the Mediterranean Sea.
