The longest recorded lifespan of a tuatara is about 80 years. Most authorities think 100 years is possible but more than that seems to be pure speculation. Reptiles in general can have longer life spans than similarly sized mammals, and this is probably down to their metabolisms' being much slower so that cell damage is less likely to occur. I think you may mean 'Why has the species remained unchanged for 200 million years?' This is because their environment didn't change very much until very recently, so there was no evolutionary pressure to change.
They live for 35 years.
They can live for 25-50 years.
alligators can live up to ? years.
That rather depends on which species you're asking about. Some species live less than ten years, while the larger pythons can live more than forty years. I have African Rock Pythons in my collection that were at least ten years old when I got them - and they've been with me more than twenty years now !
Jaguars can live for 20 years in a Zoo!And 11-12 years in the wild!Jaguars live between 20 and 25 years in the wild12-15 years oldthey can live up to about 20 years in captivity but in the wild 12 years
The average lifespan is about 60 years, but they can live to be over 100 years old.
No. The Tuatara is found only in New Zealand.

Giant Tortoises can live to be almost 200 years old. The oldest known tortoise is believed to be 182. It is believed that the Tuatara can live to 200 years old given the right circumstances.
New Zealand * Added - The tuatara, also called the sphenodon, still lives in New Zealand.

Tuatara (a New Zealand lizard) generally live to about 60 years old, though they can live to 100. In captivity a tuatara might live for 200 years according to experts. To get the average age, add up all the ages of all tuataras and then divide by the number of animals. The answer is probably about 40 years old.

Tuatara are terrestrial reptiles, living on land. They lay their eggs in burrows, find their food on land and shelter on land.
Tuatara are very primitive lizards which can grow up to 2 feet or a bit longer. They live on small animals and insects. They mature sexually in about twenty years and the females lay eggs every 4 years. They are thought to have a lifespan of about 50 - 60 years in the wild. One example, in captivity in In Invercargill, NZ is known to be over a 110 years old.
The average lifespan is about 60 years, but they can live to be over 100 years old.
Tuatara are not extinct yet but some believe that they are going extinct.There are 2 species of them. They diverged from the lizards in the late Triassic but were never as abundant as lizards. While lizards are known to not live that long, the Tuatara may live for more than 30 years.Rats prey on their eggs as well as some juveniles.Rats were introduced to more of the islands in which the remaining Tuatara are living in so researchers believe that once this generation die out, there wouldn't be a following generation to carry on because of the rats.I'm taking a herpetology class that just answered this question by my professor-William Carey UniversityBlackout12091: Just as a slight correction to this, the Tuatarra can live well past 100 years of age. They are not even sexually mature until the age of 20.
