Do you know how long the box turtle lifespan is?

Are you aware that turtles are among the most long-lived of all animals?

These little reptiles’ longevity is nothing short of extraordinary!

So if you’re considering a box turtle as your next pet it’s important to understand that this is a long-term responsibility.

Like any pet they require quality care to ensure they live a long and happy life.

How Long Do Box Turtles Live?

Many baby turtles who live in the wild will die of exposure or predation in their first year.

But for the lucky ones who survive those treacherous early days, the common box turtle life expectancy is on average 50 years. And some can live to the ripe old age of 100!

If well-cared for, a box turtle born in captivity should live just as long as those in the wild.

However that hasn’t always been the case. Bad turtle care in the past mean that many pet turtles died prematurely.

And today, that means some people still underestimate healthy box turtle life expectancy.

Luckily we know far more now about the box turtle life cycle, and how to secure a long and healthy live for them.

How Health Affects Your Box Turtle’s Life Expectancy

Box turtles are susceptible to a number of diseases and health issues.

Some can be cured, while others will shorten the box turtle life cycle.

This study also found that eastern box turtles are on the decline due to environmental pollutants as well as disease.

A proper diet, which includes both meat protein and plant matter, plays an important role in their overall health.

An initial visit to the reptile veterinarian when you first get your pet turtle, and then regular well-being check ups will also help prevent the onset of health problems.

Box Turtle Lifespan – Protecting Against Illness

The best way to stop an illness in its tracks before it can shorten your turtle’s life is to know what you might face, and the signs to look out for.

Conditions that affect the box turtle include:

  • parasites
  • fungal infections
  • abscesses
  • dehydration
  • vitamin A deficiency
  • bacterial infections
  • respiratory disorders
  • organ failure
  • and metabolic bone diseases.

We’ll look at the most common of those in closer detail.

Metabolic Bone Disease

Metabolic Bone Disease is one of the most common pathological conditions found in reptiles kept as pets.

It is caused by a calcium, phosphorous, and vitamin D imbalance in their diet, and/or inadequate exposure to UV-B light.

The disease can affect your box turtle’s shell, beak, bones, and nails.

Visible symptoms, include a soft, deformed shell, nails that curve outward, a beak that resembles a duck’s bill, or splayed legs.

However once these signs appear, the disease is probably quite advanced.

You cannot repair a shell that’s deformed, but you can prevent it from getting worse by adding a calcium supplement to his diet and ensuring he has enough UV-B exposure.

If you notice any of the symptoms, take your turtle to the vet for a proper diagnosis, and a care plan to bring him back up to strength.

Respiratory Diseases

Respiratory diseases are very common in the box turtle.

Serious respiratory infection can be fatal if not treated properly and in a timely manner.

Causes vary from viral, fungal, or bacterial infections to poor living conditions that are too cold or damp.

A sure sign of a respiratory infection is wheezing.

Other signs include: breathing trouble, swollen eyes, runny nose, inability to swim properly or buoyancy issues, and fluid or bubbles coming from the mouth or nose.

A veterinarian will usually prescribe antibiotics to clear up respiratory a infection.

Ulcerative Shell Disease

Ulcerative shell disease is also known as shell rot.

The disease usually occurs if the outside protective layer of the shell that protects the turtle’s bones and organs is injured or infected.

Even a seemingly minor injury can put your box turtle at risk of bacterial infection or disease, if it penetrates the shell and allows pathogens to enter into the soft tissue beneath.

Shell rot can also occur if your turtle is in an environment where the shell is unable to dry out and bacteria or fungus can get into the shell and cause infection.

SCUD (Septicaemic Cutaneous Ulcerative Disease) is a more serious version of this condition where bacteria grow in the bloodstream.

It can be fatal if pathogens attack your box turtle’s organs.

If you notice any injury to your turtle’s shell take him to the veterinarian.

Aural Abscesses

Aural abscesses are common in box turtles.

Visible swelling occurs when pus inside the ear canal pushes on the skin.

Box turtles are extremely susceptible to Vitamin A deficiencies and this can cause structural abnormalities in the middle ear.

If it becomes damaged, bacteria can enter and cause infection.

Although not fatal, ear abscesses weaken turtles’ immune systems and make them more susceptible to other ailments.

Treatment of aural abscesses usually requires surgery to drain the pus.

Box Turtle Life Expectancy

Box turtles enjoying a suitable habitat and a healthy diet can live in excess of 50 years.

As well as meeting their care needs, recognizing signs of disease quickly and getting prompt treatment is one of the best ways to secure them the longest life possible.

Some health problems can be identified just by looking at your box turtle.

It’s important to pay attention to the condition of their shell. Ensure that it looks smooth, without any dry or flaky patches.

Other symptoms of illness include: weight loss, diarrhea, dry skin, watery eyes, loss of energy and excessive thirst.

Spending time observing your box turtle every day is the best way to notice changes that might signal health issues.
