How Do Turtles Live So Long?

The video explores the remarkable longevity of turtles, particularly the Seychelles giant tortoise named Jonathan, who is 186 years old. Turtles exhibit negligible senescence, meaning they age without the typical decline seen in other species. This is attributed to their ability to manage oxidative stress and maintain cellular health through slow metabolism, production of telomerase, and antioxidants. Turtles can survive without oxygen for extended periods, which may have led to their longevity. While these adaptations offer insights into aging, they cannot be fully replicated in humans.

What is the term used to describe the ability of turtles to remain healthy and reproduce despite old age?

• Oxidative stress

• Telomerase activity

• Negligible senescence

• Reactive oxygen species

How do turtles manage to produce fewer reactive oxygen species?

• By having a fast metabolism

• By being poikilothermic

• By consuming more calories

• By increasing telomere length

What role does telomerase play in the longevity of turtles?

• It increases oxidative stress

• It accelerates cell division

• It prevents telomere shortening

• It shortens DNA telomeres

Why might turtles have developed strong antioxidants and proteins?

• To survive without oxygen

• To enhance their metabolism

• To increase their body temperature

• To improve their immune response

What is a potential benefit of studying turtle longevity for humans?

• Achieving immortality

• Increasing calorie intake

• Becoming poikilothermic

• Maintaining fitness in later years
