Do turtles can live a 100 years?

It is possible for a turtle to live that long, but unlikely. American box turtles usually live to be only 40, but have been known to live up to 100 years old, and sea turtles are estimated to live to about 80 years old.

Keep in mind the difference between a turtle and a tortoise. Turtles live primarily in the water (sea turtles in the ocean and fresh water turtles in rivers and lakes) and have flatter shells, while tortoises live primarily on land (deserts, for example) and typically have dome shaped shells.

Tortoises often live to be over a hundred years old, the oldest tortoise ever recorded was an Aldabra tortoise that lived and died in a zoo in Kalkutta, India at 256 years old. It was named "Adwaita" which means "the one and only" in Sanskrit.
