RESEARCH: Why does the Giant Tortoise live for a century or more?

Why does the Giant Tortoise have a long life span? 

Why does the Giant Tortoise, particularly the Galapagos Island Giant Tortoise, a land tortoise, live for a century – a 100 years – or more? 

An individual Pinta Island Giant Tortoise (Chelonoidis abingdonii), called Lonesome George, died in 2012, at the age of 100 or more. Scientists used his body for research to determine why he lived so long.

Fallacy: Tortoises will come out of their shell if they are frightened

Tortoises and turtles will come out of their shell if frightened. This is not true. This is a fallacy.

Actually, the reverse is true. Tortoises pull their head and feet into their shell so that predators cannot harm or eat them. They are too slow to run away, so hiding in their shell is their way of protecting themselves.
