The longest living animals on Earth are fascinating because none of us live long enough to see one being born and dieing of old age. Most of them have impressive sizes but, also, many of them are endangered species, despite their long life span. Here they are:
1. Ocean Quahog
The Ocean quahog, the animal with the longest life span on Earth, is nothing more than an edible mollusk. It may reach as much as 400 years .This happens because the body of this animal simply does not get old.
2. The bowhead Whale
This 20 meters whale, which can weigh up to 70 tones comes only second after the biggest of them all, the blue whale. Even though it was believed that it can live up to 70 years, new research estimated its life span at 211 years.
3. Rougheye Rockfish
Same as its relatives(different species of the same genus), the Rougheye Rockfish may expect to live long, if it isnt caught by fisherman, of course! Its life duration is estimated at 205 year.
4. Red Sea Urchin
The Red sea Urchin, one of the animals with the longest life expectation on Earth, may be found in the Pacific Ocean and has no eyes or nose or legs. It does have a mouth though, which is surrounded by 5 teeth. It may live up to 200 years.
5. Galapagos tortoise
The longest living vertebrate is the famous Galapagos tortoise, the largest species of tortoise in the world, which, despite its huge life expectation, of 177 years, it is an endangered species, counting only 3000 individuals.
6. Shortraker Rockfish
The Shortraker Rockfish may reach a length of over 1 meter and weighs 20 kg. This fish is said to touch 157 years, but it is more probable that it will reach somebody’s plate much earlier than that.
7. The Lake sturgeon
The North American Lake Sturgeon, one of the longest living animals on Earth, is also an impressively large fish. Though it lives up to 152 years, its population is in decline because fishermen do not take into consideration the fact that it does not reproduce until it is about 75-100 years old!
8. Aldabra giant tortoise
The Aldabra giant tortoises live on the Aldabra Atoll. They thrive there, because of their being protectedagainst man’s influence and their population reaches more than 100,000 tortoises. Even though their life expectation is estimated at an average 152 years, it is reported that some surpass that age. For example, the longest living tortoise in the world today is an Aldabra exemplar called Esmeralda which is thought to be 170 years old.
9. Orange Roughy
Though it is called “orange” roughy, this fish is actually red, but its color fades after death, thus becoming orange. It is expected to live over 149 years, but it grows so slowly, and reproduces so late that it needs to be protected.
10. Warty Oreo
This fish, which may be found in all the southern oceans, is not that beautiful, but it is one of the longest living animals on Earth! The warty Oreo is a predator, eating smaller fish and shrimps. It may reach 140 years.
