The world's largest turtle
The sizes of turtles vary in the world, as there is no average size for turtles, as a result of the many types of turtles, but some of them are distinguished by their very large size, and the following is a list of the largest turtles in the world arranged from largest to smallest:

The world's largest turtle
The lifespan of turtles extends to many decades, up to about 100 years and more. For example, some types of water turtles live about 40 years.
It is worth noting that the lifespan of turtles depends on several factors, including: their types, the quality of their diet, and the nature of the environment in which they live.
It is believed that the slow growth of turtles during their lifetime avoids aging, and their slow metabolism rate enables them to survive for long periods without the need for food and water, thus increasing their ability to resist difficult living conditions, and large turtles live a longer life compared to the small size.
The Turtle Conservation Society indicates that the average lifespan of most species of turtles ranges between 10-80 years , with the exception of large sea and land turtles, as they can live longer life that may exceed 150 years, and a group of turtles have lived to very large ages that exceed the average lifespan of natural turtles .
