How long do turtles live?

How long do turtles live?

Turtle life spans range quite broadly anywhere from 15 – 30+ year. Turtle & tortoise species are among the longest-living animals on planet earth.

Turtles live longer than most pets we have around the house. Many species normally kept as pets can easily live well into their 30s.

A turtle’s lifespan needs to be taken into consideration when acquiring a turtle. Also, if you can no longer care for your pet turtle it’s best to find a good home for your pet turtle when you can no longer care for it.

You can check our adoption page for people giving up and wanting turtles. Check the comments at the bottom.

Turtles should never be released into the wild. The turtle will likely not survive, and if it does could wreak havoc on the local ecosystem.

A captive turtle’s lifespan is also determined by factors such as its enclosure, diet, and care.

Musk turtles are closely related to mud turtles. In fact, both turtles belong to the same family – Kinosternidae. Musk turtles belong to the genus Sternotherus.

The razor-backed musk turtle (S. carinatus) is one of the more popular musk turtles kept as pets. While there is little information on their lifespan estimates ranges from 20 years to 50 years. According to (Franklin, 2015), the longest lifespan on record is 29 years in captivity. Their lifespan in the wild is unknown.

The flattened Musk Turtle (S. depressus) specimens have lived to over 20 years in captivity. Little is known about the lifespan of the critically endangered flattened musk turtle species in the wild.

The painted turtle (Chrysemys picta) is common in North America. Belonging to the genus Chrysemys, the painted turtle is one of the turtles commonly kept as pets.

There are four subspecies based on geographical locations. These include the eastern painted turtle (C. p. picta), the midland painted turtle (C. p. marginata), the southern painted turtle (C. p. dorsalis), and the western painted turtle (C. p. bellii).

Growth rings can be used to determine the age of painted turtles below the age of four. For adults, growth rings can be used to estimate their age.

According to studies, painted turtles can live to be over 55 years. The average lifespan of painted turtles in the wild and in captivity is 35 to 40.

Although pond sliders are among the most popular turtles kept as pets, determining their maximum lifespan can be tough as owners tend to exaggerate the age of their pets.

Also, owners are known to release sliders into the wild. However, the data available suggests that captive sliders can live up to over 40 years. In the wild, sliders can live to 30 years.

Diamondback Terrapin

Best Practices For Attaining Long Lifespans

Proper Feeding

It’s important to properly feed your turtle if you want it to live a long and healthy life. Many turtles aren’t picky eaters and will accept whatever you offer them.

However, that doesn’t mean you should feed them whatever you get your hands on. Foods that might be healthy for you could prove to be unhealthy for your turtles.

For instance, many fruits and vegetables such as tomatoes, apples, and many others can be too high in sugar to be a staple food. Similarly, iceberg lettuces isn’t nutritious enough for turtles.

Here is what you need to do.

1. Research the ideal diet for the turtle species

Be sure to feed your turtle the best foods for it. This involves thorough research. Many turtles are omnivores and as such accept both animal matter such as insects, fish, and meat, and plant matter.

It is best to feed your turtle a lot of leafy greens as well as aquatic plants. In addition to this, you can offer commercial turtle diets. A proper mix ensures the turtle acquires all the needed nutrients needed in the right amount.

You can get a good idea of what turtles eat here.

2. Vitamin Supplements

Regardless of how well you think you feed your turtles, they may still need nutrient supplements, in particular vitamin D3, calcium, and vitamin A. Deficiencies of these key nutrients can lead to serious health issues and even death.

UVA/UVB lighting for indoor turtles ensures that they can synthesize vitamin D3. even with that, it is wise to supplement the diets of turtles housed indoors with calcium & vitamin D3 as well as vitamin A.

For turtles housed outdoors, vitamin D3 supplements aren’t necessary, but it’s still prudent to supplement their meals with calcium and vitamin A.

Getting The Enclosure Right

The enclosure of the turtle needs to be large enough. As you may know, every turtle species requires differently sized enclosures. However, the adult size of the turtle can be used as a guide to determine the right size for the turtle tank.

As a rule of thumb for every inch of the turtle’s length, provide about 10 gallons of aquarium shape. As such for a turtle that is 5.5 inches in length, provide a 55-gallon aquarium.

If you have several turtles in an enclosure, for every additional turtle add about half the original tank capacity.

In addition to the size of the enclosure, the location of the enclosure is also key. The enclosure needs to be placed in the shade, and not in the direct path of sunlight.

A small enclosure can stress out the turtle and significantly affect the health of the turtle.

Keeping A Clean Aquarium

how-to-clean-a-turtle-tank-1

A clean enclosure can help prevent infections and other health complications.

Clean the aquarium every month.

Also, change about a third/quarter of the water in the aquarium every week.

Install a powerful filter. Turtles produce a significant amount of waste. In order, to keep the enclosure’s water clean, ensure that it is well filtered.

See our best filter for turtles review for more on that.

Since turtles produce more waste than fish do, the filter used needs to be more powerful than normal. For instance, for a 50-gallon aquarium, get a filter designed for a tank with a capacity of 100 gallons.

Dirty living conditions and stress can shorten the turtle’s lifespan.

Check this cleaning guide for more details.

Conclusion

Turtles are among the most popular reptiles kept as pets. They are also known for their long lifespans. You need to keep this in mind when adopting a turtle. On average, expect your pet turtle to live to be 30 years.

Tortoises live even longer, up to 100+ years.

If you want to keep your turtle stress-free and healthy you need to ensure that it is kept in a clean enclosure and fed a healthy diet.

Additionally, conditions such as temperature and lighting need to be right. Regular vet visits can also help ensure that the turtle lives as long as possible.
