Turtles can live up to 500 years
These animal species get particularly old
Some animals reach an age that we humans can only dream of. Beatrix Köhler, the zoological director of the Munich zoo Hellabrunn, told BR24 that the life expectancy of animals is mainly from three factors depends:
- Heart rate and metabolism
A slow heartbeat makes for you slowed metabolism, who in turn has the Decelerates the aging process. Animals with a high heart rate, however to hibernate, also have a relatively high life expectancy. Large animals tend to live longer than smaller ones.
But some animals have developed other clever strategies to increase their life expectancy. Find out here which animals can get particularly old.
African elephant: 70 years
The African elephant proves that large animals can live to be extraordinarily old: These sociable pachyderms can live up to 70 years and are therefore the land mammals with the highest life expectancy.
They only reach their full size when they are around 15 to 25 years old and then continue to grow slowly until they die.
Kakapo: 90 years
The kakapo is a flightless bird native to New Zealand. Weighing in at around three kilograms is the kakapo the heaviest of the parrots. Although it has a life expectancy of around 90 years, the bird is unfortunately threatened with extinction.
Bridge lizard: 100 years
The bridge lizard grows only slowly and reached sexual maturity at around 20 years of age. she can over 100 years old and can be found on smaller islands off New Zealand. For 225 million years there is the bridge lizard on earth. Unfortunately, the species is now threatened with extinction.
Bowhead whale: 200 years
The bowhead whale is that Mammal with the longest life expectancy. Whalers found harpoons and spearheads from the 19th century in the whale blubber - the animals are over 200 years old.
With a length of 20 meters and weighing up to 100 tons he is a real ocean giant. The bowhead whale feeds mainly on small crustaceans. In order to satisfy its appetite, the animal has to do it eat almost continuously.
Galapagos giant tortoise: 270 years
Of course, turtles should not be missing from the list of the oldest animals. While some species like the Seychelles giant tortoises up to 100 years old a Galapagos giant tortoise reached her at Cairo Zoo in 2006 270 years of age.
Greenland Shark: 500 years
The Greenland Shark has that highest life expectancy of all vertebrates. Researchers at the Greenland Institute for Natural Resources examined female Greenland Sharks and found that it was the oldest specimen at least 272 years old had to be. The scientists assume, however, that the animals up to about 500 years old can be.
Bowhead sharks live in the Arctic Ocean off the coasts of Canada, Greenland and Norway. The icy temperature of the water makes for you slowed metabolism. As a result, the animals age more slowly.
Coral: 4,000 years
Corals are marine animals that feed on plankton. When investigating the coral genus Gerardia, scientists found that the animal between 2,700 and 4,200 years had to be old. These corals grow very slowly: In a year they only get about 35 microns larger. That is just about the size of about three grains of dust.
Sponge: 10,000 years
A Giant sponge supposed to be at the bottom of the Antarctic Ocean about 10,000 years old be. Sponges are mindless animals that are found in all seas on earth.
They create with their small chambers Habitats for many other marine life and the substance they secrete for defense has been in the for decades medical research examined.
Tardigrade and jellyfish: theoretically immortal
There are indeed animals that theoretically live forever. That includes that Tardigradethat is not even a millimeter in size. It lives in the sea, in freshwater and humid land areas. The animals are only active when it is wet and can do themselves to be awakened after 30 years of absolute dryness. Even high pressure, radiation and a lack of oxygen do not mind the tardigrade or water bear.
Also the small jellyfish Turritopsis dohrnii is biologically immortal. The approximately three to four millimeters large animal can reverse its life cycle and rejuvenate with it. If the jellyfish is not eaten or washed ashore, it theoretically lives indefinitely.
