Looking for some super cool Galapagos tortoise facts? You’ve got them; enjoy!
The Friendly Giant
The Galapagos tortoise is quite the sight; tall, scaly, and nearly pre-historic, it makes an entrance. They are the biggest tortoises in the world and among the longest-lived.
Many people think that tortoise equals slow. However, the Galapagos tortoise went a lot faster than my cartoon-influenced 12-year-old self expected.
So while you certainly won’t catch them winning any sprints, they can go a lot faster than you might expect.
Galapagos Giant Tortoises by the Numbers
- Latin name: Chelonoidis nigra
- Length: Males may grow up to 6 ft (1.8 m) long and 4-5 ft (1.2 – 1.5 m) wide. Females are generally smaller, even half the size of males.
- Weight: Males can weigh nearly 600 lb (272 kg), although they normally stay around 500 lb (227 kg). Females can weigh up to 300 lb (136 kg) but average 250 lb (113 kg).
- Color: Galapagos tortoises range in color from a dark blackish shell to a dusty brown head, neck, and legs, with some of the scales being a darker brown. Their faces may frequently be stained green from all the grass they’ve been munching.
- Cool feature: Galapagos tortoises live well over 100 years in the wild. The oldest recorded is said to have lived at least 170 years.
As you’ve probably figured out by now, Galapagos tortoises live in the Galapagos Islands, off the coast of Ecuador.
13 Awesome Galapagos Tortoise Facts
1. Galapagos is named after its tortoises.
The word “Galapagos” comes from the old Spanish word “galapago,” which the original explorers used to mean “saddle” due to the shape of the tortoise’s shells.
When the islands were first discovered, people used to ride the saddleback tortoises; however, this is now illegal because it’s very bad for the tortoise.
2. Unlike cartoons, tortoises are stuck in their shells.
Their shell is actually attached to their ribs, so unless you’re into zombie tortoises, they are staying put!
3. The Galapagos tortoise shell is not solid.
Although these animals are very heavy, their shell is not the biggest culprit. The shell is made up of honeycomb shaped air chambers.
While this lightens the load significantly, the tortoise’s ability to lift itself is still a sight to behold. I know I’m certainly not as strong as these gentle giants, but I couldn’t lift up that shell.
Then again, a skinny, muscle-less, twelve-year-old girl wasn’t meant to lift a giant tortoise shell.
Some scientists believe that some tortoises may have gotten dumped off of boats near Wolf Volcano by whalers.
And then arrived on Isabela Island in Galapagos by floating on their backs with their long necks pointed straight up. Good for them; they didn’t become tortoise meat!
4. Galapagos tortoises are ferocious fighters…?
A Galapagos tortoise “fight” is quite a spectacle. The males will glare at each other, open their mouths, raise their heads as high as tortoise-ly possible, and then… that’s it. Highest head wins! The loser will suck his head in and slink away.
A much smaller male with a longer neck may end up beating a very large male if he can raise his head high enough. If only men were as smart as tortoises the world would be a much more peaceful (and tall) place.
5. Why do Galapagos tortoises hiss?
The short answer is, they don’t. The impressive hissing noise occurs when they pull their heads back into their shells.
They release the air in their lungs so they can have room for their heads, and this is what makes the hissing noise.
6. “Honey, what’s for dinner?”
Galapagos tortoises can go for a whole year without food or water. How do they do it?
Their bodies slowly start breaking down their body fat, which produces water as a byproduct, allowing them to survive. How crazy is that!
7. Scales and scoots!
The skirt-like edges (scoots) on the shell of the Galapagos tortoise will wear down as the tortoise gets older, and the scales on the fronts of their legs will do the same.
The young tortoises have scales on their legs to protect their face and neck when they suck themselves into their shells.
8. An adult Galapagos tortoise has no natural predator.
While baby tortoises have lots of threats (see fact #13), the adult Galapagos tortoise has almost nothing to worry about.
Which is good, because their protective scales and scoots wear down as they get older.
9. Weird feeding habits of the Galapagos tortoises.
Galapagos tortoises are herbivores and enjoy eating grass, fruit, leaves, flowers, cactus, and prickly pear – a fruit that grows on cactuses.

10. Galapagos tortoises begin their lives in a pee-soaked sand hole.
The mother digs a hole in the sand and promptly proceeds to pee all over it. Thanks a lot MOM. This is done so that the sand won’t collapse on the eggs. She then buries her eggs 12 inches (30 cm) deep, and then covers them with sand.
Galapagos tortoises lay up to 16 eggs. Yikes! I’m glad I don’t have 16 siblings. The eggs are hard-shelled and about as big as tennis balls.
11. Warm sand = more females.
The temperature determines the gender of the hatchlings! If it’s warmer, more females will hatch.
Of course, the reverse is true: cooler sand temperature means more males. When I first heard about this, I couldn’t believe it.
12. Baby Galapagos tortoises have to dig their way out of the nest.
This process can take up to a month. To survive, they feed on their yolk sac (which can last up to seven months).
Imagine if we had to dig our way out of our… hang on, that’s just getting weird.
13. Galapagos tortoises are vulnerable
These beautiful animals have been classed as “likely to become endangered.” When Charles Darwin visited the islands in 1835 there were 15 different types of giant tortoises in the Galapagos.
Now, there are only 11 kinds, and some of these are on the brink of extinction.
Through out the 17th to the 19th centuries, they were hunted for food, with possibly 100,000 being killed. Now, introduced pigs, dogs, goats, cats, cattle, and rats threaten their eggs and eat their food.
Despite the positive effects of captive breeding at the Charles Darwin Research Station in the Galapagos, the help of some zoos, like the San Diego Zoo (which has the largest population of captive Galapagos giant tortoises), there are only about 15,000 Galapagos tortoises left in the wild.
