The longest living animals on our planet have an age that is far from one century old. Such records can not boast any long-lived man. Scientists are still struggling over the question of the secret of the longevity of these creatures, but they can not find an answer so far. Perhaps, mankind is not far from the great discovery, allowing to reveal the secret of eternal youth, which some individuals possess. Here is the list of top 10 longest living animals in the World.
Top 10 longest living animals in the World

The list of top 10 longest living animals in the World starts with the European Proteus which is one of the longest living animals on Earth, which can reach the age of a hundred. The habitat of this unusual creature, also referred to as human fish due to the color of the body, is the ponds in the caves. European proteus has small dimensions that do not exceed 13 centimeters. On the body there are two pairs of legs that have fingers. The uniqueness of this animal lies not only in longevity, unusual appearance, but also in the ability to perceive the environment – the organ of vision in the proteus is almost not developed, so perception is through photosensitive cells located throughout the entire surface of a small body.
We have Tuatara at 9 in this list of top 10 longest living animals in the World. The Tuatara or Hatteria rightfully refers to the long-livers of the planet, whose age can reach up to 200 years.

These are large enough reptiles whose length can reach 80 centimeters. Sexual maturity in individuals of this species occurs by the age of twenty years. They reproduce very slowly. After mating with the male, the appearance of eggs and before hatching takes more than 1 year. Currently, these animals are listed in the Red Book, as they are threatened with extinction
Guidak , which in translation means “deep digging” – is one of the longest living mollusks on the planet, whose average life expectancy is 145 years. However, there were recorded cases of animals of this species, whose age reached 160 years. Among the existing versions of longevity, the main are two – sluggish metabolism and the lack of enemies. These are rather unusual creatures that have long intergrown siphons, capable of reaching up to 1 meter in length. At the same time they have a small and very fragile shell of 20 centimeters. For all their longevity, the Guidiak produce about 5 billion eggs for the continuation of the offspring.

Red sea urchin is equated with the long-livers of the planet. The age of some individuals can reach 200 or more years. The habitat of these creatures is the Pacific Ocean, near the western coast of North America. They prefer shallow water at a depth of 90 meters and live where there are practically no waves. These amazing living individuals move along the seabed with their thorns, located on the entire surface of the body. Echinoderms are relatively small in size, which can range from 2 to a couple of dozen centimeters. Sea urchins are not choosy in the diet and almost eat everything that comes across them, both from plant and animal food.
6.Greenland whale –
The Greenland whale is a marine mammal, which also belongs to a number of long-livers of the planet. The age of this vertebrate creature can exceed 200 years. The oldest recorded record holder survived to 211 years. The Greenland whale prefers the cold waters of the Northern Hemisphere. However, for their predilection these animals do not like to be in the midst of the frozen ground, so sometimes they have to split the ice floes to make their way further. Because of the fact that the bowhead whales live in harsh conditions, it is quite difficult to monitor them.
5.Carp Koi –
Carp koi is one of the most long-lived animals, which in addition has a very interesting and diverse color. This fish has more than 14 colors. Koi carps belong to domesticated ornamental fish that were introduced to China 2,500 years ago. The peculiarity of these water creatures is their ability to live up to 200 or more years. One of these long-livers is a fish named Hanako, whose age was 226 years. The age calculation for koi carp is carried out according to the number of rings that are on their scales.
4.Abingdon’s Elephant Tortoise –
Abingdon’s elephant tortoise is one of the longest living vertebrates that lives on our planet. Representatives of this species can survive up to 150 years or more. One of these long-livers is the tortoise Garrietta, which was born around 1830. At the time of death, her age was 250 years. Garrett died in the Australian zoo from heart failure. Another long-lived of this kind is the turtle Advaita, who died about the same age as the previous long-loner.
3.Greenland Polar Shark –

On the 2nd place in this list of top 10 longest living animals in the World we have Medusa Turritopsis nutricula,which belongs to almost immortal animals, since it is capable after transition to sexual maturity to move to the polyp stage and back. That is why this animal has no natural restriction on its life expectancy. Now scientists are actively studying this type of jellyfish, which possibly will help reveal the secret of how you can reverse the aging process.
1.Oceanic Venus –
Oceanic Venus refers to the genus of bivalve mollusc, which lives in ocean waters. This is the most long-lived creature on Earth, known to science. Age of the vein can exceed 500 years. The average duration of these molluscs are 400 years. The champion among the representatives of this species was the mollusk, who was named Ming, his age, according to scientists, was 507 years.
