Ever wonder why some animals live longer than others? Below we’ll cover a variety of species and the average lifespan so you can understand how other animals live longer than others.
The Longest Living Animals in the World
1. Tuatara
The Tuatara, a unique lizard-like reptile native to New Zealand that existed since the Triassic period, when ocean floors were vastly different, has one of the most extended life spans among animals. Genome sequencing analysis shows that this particular species is endowed with more genes related to longevity than other vertebrates—making them very interesting for human aging genomic research purposes.
Henry’s mating at 111 years old proves their distinctive life cycle compared to Hanako, a koi fish reaching 226 years in age. This made the Tuataras join up as among some of Earth’s most incredible living creatures outlasting many others from regions like South America or ones who inhabit underwater environments around oceans across the globe.
2. Seychelles giant tortoise: 190+ years old
Giant tortoises from Seychelles are renowned for their incredibly long life expectancy, which is known to exceed 190 years. The most elderly living terrestrial animal recognized till now is Jonathan, an Aldabra giant tortoise, who has reached the impressive age of 183 years. This remarkable longevity increases even more when put side by side with Galapagos’ giant tortoise, whose documented age reaches 255 yrs.
Body size plays a significant role in deciding how long other animals can live. Some species, such as immortal jellyfish, possess amazing abilities to exist perpetually. In contrast, decreased body temperature tends to equate to extended lifespans seen among particular creatures like Wisdom, the oldest extinct wild bird, which is one example of that fact.
The undeniable capability demonstrated by Seychelles’ giant tortoises living beyond the 190s implies resilience and flexibility regarding conforming to their surroundings.
