What Pet Fish Lives the Longest
E'er wondered which animals live the longest? Or how old the oldest brute is?
Believe it or not, there are sharks alive today that were around when William Shakespeare was writing his best works (more than 400 years agone)! In fact, there are a number of species with lifespans that put the oldest humans to shame.
Below we list the 12 vertebrate animals that live the longest, with lifespans of anywhere up to 500 years. Nosotros've decided to look at vertebrates simply for this article, but there are a number of other forms of life on world – particularly microorganisms, and sponges – that have been proven to live for thousands, or fifty-fifty millions of years.
For example, some endoliths (microorganisms that alive inside rock, coral and brute shells), have extremely long lifespans, metabolizing slowly with a generation time of around 10,000 years. And in July 2020 marine biologists discovered aerobic microorganisms below the ocean floor that they dated to 101.5 1000000 years former.
When it comes to animals (rather than microorganisms), drinking glass sponges found in the Southern Ocean and the East China Ocean have been adamant by scientists to be about xv,000 years sometime.
Then there is Turritopsis dohrnii – known every bit the 'Immortal jellyfish'. This unique fauna is able to cycle from a mature adult life stage to an immature polyp life phase again and over again, which means that – in theory at least – it is biologically immortal. In reality, the immortal jellyfish get injured and eaten like most other animals in the wild, and so is not truly immortal.
What animal lives the longest? The bioluminescent Turritopsis dohrnii – the 'immortal jellyfish – is perchance the longest living animal ever
With this context in mind, here's our list of the 12 vertebrate animals with the longest lifespans. For each species of long-living animal below we list both the estimated average age of the species, and the estimated longest-living known individual animate being (where this is known). Sources are provided for all ages:
12 Vertebrate animals that live the longest
Greenland Shark
Oldest known historic period: 512
Average lifespan: 200
Greenland shark – the longest living animal
According to a 2016 scientific study, the Greenland shark is the longest living vertebrate in the world by some distance. Using middle lens radiocarbon testing, a 5 meter Greenland shark was found to exist 392 years old ± 120 years. This puts the historic period range of the shark tested at between 272 and a whopping 512 years old!
Living in the Chill and N Atlantic oceans, the Greenland shark grows very slowly in the cold waters, at an estimated 1 cm a year, and doesn't reach full maturity until about 100 years sometime. They are scavengers, eating a variety of fish and birds, though due to population pass up the shark is sadly now considered most-threatened.
Giant Tortoise
Oldest known age: 255
Boilerplate lifespan: 150
Galapagos giant tortoise – the longest living land animal
Tortoises come in all shapes and sizes, with their lifespan generally linked to their size. The boilerplate age a tortoise can live to is betwixt 90 and 150 years, depending on their species, with the giant tortoises taking the crown of the oldest terrestrial animals.
Adwaita was an Aldabra giant tortoise who died at Alipore Zoo in India an estimated age of 255 in 2006. The oldest currently living land animal is thought to be Jonathan, a Seychelles giant tortoise living on the island of Saint Helena, and reported to be 188 years old.
Tortoises tend to live much longer than turtles. Want to know more differences between turtles and tortoises?
Orange Roughy
Oldest known age: 245
Average lifespan: 149
Orange roughy – the longest living fish
The orangish roughy – also known as the red roughy, slimehead, or deep ocean perch – is a relatively large deep-body of water fish weighing upwardly to vii kg. Institute in deep waters of the Pacific and Atlantic oceans the fish is a bright red colour which fades to a yellowish-orange after decease.
The orange roughy is notable for its boggling lifespan. When they were start commercial fished in the 1970s their lifespan was idea to be 30 years, but new prove has come to lite that shows they alive to exceptional ages – such as one orange roughy caught near Tasmania that was aged at 250 years.
Koi
Oldest known age: 226
Average lifespan: 40
Koi fish – super long living
Koi fish are a domesticated diversity of the mutual carp native to the Caspian Sea, and can grow upwardly to 1 meter long. Now constitute around the world, koi are particularly common as ornamental fish in ponds and artificial rock pools.
With an average lifespan of xl years in the wild, there are many cases of individual koi vastly outliving this average age. One particular Japanese koi – named Hanako – died in 1977, subsequently which a study based on the growth rings of her scales put her age at 226. It's worth noting that at that place is some controversy well-nigh this method of dating koi, so the issue is not universally accustomed.
Bowhead Whale
Oldest known historic period: 211
Average lifespan: 100
Bowhead whales – the longest living mammal
Found in the arctic regions of the Northward Atlantic and North Pacific oceans, the Bowhead whale – also known as the Arctic whale – is the longest living mammal on earth past some way.
Using chemic prove from the whales' eyes and teeth, together with dating harpoon tips lodged in their mankind, the average bowhead whale has been found to have a lifespan of over 100 years. One specific whale was dated by this method to exist 211 years old at the time it died.
Rougheye Rockfish
Oldest known age: 205
Average lifespan: Unknown
Rougheye rockfish – fish with a huge lifespan
The rougheye rockfish is named after the ten or so spines that grow on its lower eyelid. Living in deep waters in the North Pacific and growing to 0.eight meters, they feed on shrimps, crabs, and other fish.
Rougheye rockfish are recognised as being amongst the longest living of all fish and take been known to accomplish an historic period of 205 years
Tuatara
Oldest known age: 200
Average lifespan: 100
Tuatara – the long-living lizard
The tuatara is a cadger-similar reptile endemic to New Zealand, and is the last of a type of a creature that originated during the Triassic period, having diverged from other reptiles around 250 million years agone.
Tuatara can alive to well over 100 years, with Henry, a tuatara in captivity at New Zealand'due south Southland Museum, mating for the first time at the age of 111 with an lxxx-year-onetime female to father eleven babies. Their longevity has been the subject field of a scientific investigation, and during genome sequencing tuatara were shown to incorporate more genes to protect against crumbling than whatever other vertebrate.
Crimson Sea Urchin
Oldest known age: 200
Average lifespan: 100
A group of reddish sea urchins
The crimson ocean urchin is a small, spiny invertebrate that lives in shallow coastal waters around the world. A recent study concluded that the cherry-red sea urchin frequently live to be 100 years old, and some may achieve 200 years or more and still in good health. This puts them at around the aforementioned lifespan as the body of water quahog, a bivalve molusc.
Urchins in general seem to announced to be able to defy aging, being able to reproduce through their unabridged lives, and can regenerate lost body parts.
Sturgeon
Oldest known age: 150
Average lifespan: 100
A sturgeon fish
Sturgeons are referred to as 'primitive fishes' as they remain nigh unchanged since their primeval fossils, which date to around 200 million years ago at the stop of the Triassic catamenia. The fish are native to subtropical, temperate, and sub-Arctic lakes, rivers, and coastlines of Eurasia and Northward America.
Ranging two to 7 meters long, sturgeon are amongst the longest living fishes, living to 100 years on average. Female person lake sturgeon are the longest living blazon of sturgeon and tin live to be 150 years one-time.
Macaw
Oldest known age: possibly 121
Boilerplate lifespan: 35
Macaws – the longest living birds
Macaws are the largest and nigh vibrantly coloured members of the parrot family, and constitute in ranges across N and South America. In the wild macaws have a life expectancy of around 35 years, though live much longer in captivity due to the lack of predation. Information technology'due south thought that the size of the macaw is linked to its longevity – the larger the bird is, the longer its lifespan.
Whilst it's common for pet macaws to live to 70 or 80, it's possible they can live much longer. Ane blue-and-yellowish macaw called Charlie is said to have been hatched in 1899 and was once the pet of Winston Churchill (though this claim has been refuted by Churchill'due south manor). Charlie supposedly celebrated her 120th birthday at a garden center in Reigate, England in 2019.
Longfin Eel
Oldest known historic period: 106
Boilerplate lifespan: 60
A longfin eel peeps out from cover
Native to New Zealand and Australia these eels are a traditional food source for the Maori people. The longfin eel averages an age of around sixty years, and the oldest living longfin eel e'er recorded died at 106 years old. As with the Greenland shark, these eels abound extremely slowly, which helps them accomplish such old ages.
Elephant
Oldest known age: 86
Boilerplate lifespan: threescore
An African elephant has an imesnse lifespan
Elephants are the largest land animals in the world, and take an impressive average lifespan of around 60 years.
The oldest individual elephant nosotros're aware of – confirmed by Guinness World Records – was Ling Wang, an Asian elephant (Elephas maximus), who died on 26 February 2003 aged 86, at Taipei Zoo, Taiwan.
Exercise yous know all of the differences between Asian and African elephants?
Greater Flamingo
Oldest known age: 83
Boilerplate lifespan: 35
Greater flamingo wandering in a lake
The greater flamingo is the about mutual of the six flamingo species, recognisable for their long neck, pink coloring, and blackness-tipped beak with a sharp downward curve.
In the wild greater flamingos accept an boilerplate lifespan of 35 years, whilst in captivity, the birds are known to live to around lx years old. The oldest known greater flamingo – named Greater – died at Adelaide Zoo in January 2014 at the age of 83.
