Why Do Tortoises Live So Long?
The lifespan of a tortoise depends primarily on its subspecies. While some tortoise species live 30 years, many of them have a longevity of over 100 years.
But if you consider the overall life expectancy of tortoises, they live longer than many other animals on the planet. Have you ever thought about why tortoises live so long?
Well, there is not one particular answer to this question. But we can point out multiple factors behind the tortoises’ long life expectancy. Such as,
1. Slow Metabolism
Apparently, the slow metabolism of the tortoises helps them live longer. Though there is no strong evidence to back up this statement, it is an educated guess from the experts.
See, tortoises can slow down their heart rate, oxygen consumption, and activity level, depending on the weather. Because of the slow down metabolism, tortoise cells stay intact for the longest time. As a result, these creatures live longer.
So, a tortoise with slower metabolism should live longer.
Compared to tortoises, humans have a fast metabolism. Hence why we do not live for centuries.
According to another belief, the bigger size benefits the tortoises with a longer lifespan. Like the previous factor, this one is also an educated guess. However, if you go through the size and lifespan chart of different tortoises, you will clearly notice the links.
I think the bigger tortoises live longer as they can save themselves better. For example, the predators do not go after the big tortoises. Instead, they look for a small one, which can be easily turned into a feast.
3. Delayed Reproduction
The delayed reproduction is definitely a reason why tortoises live so long.
See, tortoises in the wild are busy arranging their meals. So, reproduction is the last thing on their mind.
Most tortoises gain sexual maturity at the age 5 – 7 or by 15. Even after becoming sexually active, tortoises are in no rush to increase their population. Even if you look at the numbers, only 1% of the tortoise egg clutches actually make it to adulthood.
Simply speaking, delayed reproduction, fewer populations, and longer lifespans are the result of evolution.
Tortoises live in locations where they can flourish flawlessly. It helps them live longer.
5. Self Defense Mechanism
Tortoises are not the fastest runner, for sure. But when under attack, they do not have to run. Instead, they can easily hide in their shells and avoid the situation.
While most wild animals are exposed to predators, tortoises are born with defence mechanisms. Scientists suggest that these shells can carry 200x the weight of their own. Can you imagine how strong the tortoise shells are?
As tortoises can avoid predatorial attacks more easily, they have higher chances of living longer.
6. Healthy Lifestyle
Tortoises are herbivorores. Their diet includes mainly grass, hay, vegetables and fruits. Because of this healthy and green diet, tortoises are blessed with a long life expectancy.
7. Chilled Guy
Stressing is never good. Your life gets complicated and stressful when you start socializing. This is true for the tortoises too!
But fortunately, tortoises are not the friendliest creatures. In fact, these reptiles prefer living alone. Hence, they are away from the power game and live a healthy, long life.
How To Make Your Tortoise Live Longer?
You know why a tortoise and a turtle live so long. Yes, external factors play a key role in their extended longevity. However, proper care and attention to these creatures can also help achieve a long life expectancy in captivity.
Here is how you can make your tortoise live longer,
1. Feed The Tortoise An Appropriate Diet
Tortoise’s diet has no similarity to the turtles’. While most turtles are omnivorous, tortoises live on greens.
The meal chart of most tortoises includes the following safe items,
- Aloe vera
- Cactus pads
- Butter lettuce
- Collard greens
- Edible flowers
- Hedge mustard
- Sea holly
- Sow thistle
- Sweet potato
- Alfalfa hay
- Oat hay
- Rye hay
- Oat hay
- Meadow hay
- Timothy hay
- Bermuda grass, etc.
So, the tortoises basically survive on grass and vegetables. Most species do not ingest any animal protein. Hence, make sure their meals are all green. Besides, these creatures need supplements in captivity to back up any mineral deficiency.
Again, you have to follow an ideal routine to feed the tortoises. For example, a healthy tortoise requires feeding only 5 days a week.
Drafting a tortoise’s meal plan is challenging. Considering this, I have made a detailed guide on the tortoise’s feeding habits. You can check the article from this link. Also, if you have a baby tortoise, go with this write-up.
2. Proper Habitat Set Up
In the wild, mother nature provides the tortoise with everything. But in captivity, you have to put together everything to replicate the wild touch in the enclosure. If the habitat lacks anything, it can affect the pet’s lifespan.
Hence, ensure that the pen includes the following supplies,
- A spacious hole or a dog house
- A spacious yard
- A shallow water source for drinking and bathing
- UV lamp
- Heating lamp, etc.
Remember, direct sunlight is mandatory for tortoises. If you raise the pet in an outdoor habitat, you do not have to worry about that. However, in the case of an indoor enclosure, install a quality UV and heating light.
3. Keep The Pen Clean
Though tortoises are hardy creatures, they can not stand filthy enclosures. Again, a dirty environment can entice bacterial growth, causing the pets to have infectious diseases. Hence, you have to focus on the cleanliness of the habitat too.
4. Do Not Stress The Pet
Stressing the tortoise can impact its lifespan. The scarcity of food, congested space, frequent touch, no medical care, etc., make the tortoise anxious. As an owner, you should make sure that the pet is not stressed or scared in any situation.
5. Medical Emergency
The captive tortoises have access to medical care. It is a primary reason why they live longer than wild tortoises.
You must take your tortoise for a regular medical check-up to keep it in good health. Only then can the pet enjoy a long lifespan.
Life Cycle Of A Tortoise’s Life
We can divide the life cycle of a tortoise into 4 major stages. Such as,
- Nesting: The life of a tortoise starts as an egg. During the nesting season, the gravid tortoises lay eggs and leave the spot.
- Hatchling: The babies come out of the eggs within 90 days. The hatchlings are most sensitive to the environment.
- Juvenile: During this stage, the tortoises focus on their growth.
- Adulthood: Tortoises consider mating and growing their population at this point of their life.
How To Tell The Age Of A Tortoise?
It is nearly impossible to tell the age of a tortoise from its appearance. Unless you have marked the birth date of a tortoise, there is no way you can say its exact age.
However, cheat methods can give you an educated guess of the tortoise’s age. But those are not reliable. For example,
- Comparing the growth chart
- Counting the growth ring
How do these techniques work? Read my previous article for details.
The average lifespan of tortoises is 50 – 100 years. While many species live for centuries, some can only reach the 30s. Thus, the tortoises’ longevity depends on the subspecies and care available to the creatures.
