Galapagos tortoises are cold-blooded animals (they do not have stable body temperature).

What is unique about Galapagos tortoise?
The giant tortoises of Galapagos are among the most famous of the unique fauna of the Islands.Saddle-backed shells evolved on the arid islands in response to the lack of available food during drought.
Are Galapagos tortoises warm blooded?
Like other reptiles, Galapagos tortoises are cold-blooded animals. They spend much of their day soaking up the sun to warm themselves. When the sun goes down and the temperature cools, tortoises sleep partially submerged in mud, water or brush to keep warm.
Are Galapagos tortoise cold-blooded?
Galápagos tortoises tend to lead a peaceful, quiet life that centers on eating, relaxing in the sun, or wallowing in puddles. Because they are cold-blooded like other reptiles, they like to soak in the sun to warm up. At night, they may rest partially submerged in mud, water, or brush to keep warm during cool evenings.
Is Galapagos tortoise amphibian or reptile?
On islands with humid highlands, the tortoises are larger, with domed shells and short necks; on islands with dry lowlands, the tortoises are smaller, with “saddleback” shells and long necks.

What are 3 characteristics of the Galapagos tortoise?
Shell functions (Chiari et al. 2009)
- Protection.
- Regulation of body temperature (thermoregulation)
- Facilitation of mating and reproduction.
- Ability to turn over (“self-righting”)
- Locomotion.
- Storage of water, fat, and wastes.
Why do tortoises in the Galapagos look different?
Galapagos tortoises have two very different shapes, each adapted for different feeding habits needed on low, arid islands versus high, lusher islands.
Does anything eat Galapagos tortoises?
The only native natural predator of the Galápagos tortoise is the Galápagos hawk. The hawk preys on eggs and newly hatched tortoises. The main threats to adult tortoises are habitat destruction and illegal hunting.
Do Galapagos tortoises hibernate?
Since tortoises hibernate to make it through cold and harsh months, it stands to reason that tortoises in hotter climates are less likely to hibernate.However, even desert and tropical species can hibernate. Species requirements are just as important as outside factors, such as weather and temperature.
What do Galapagos tortoise need to survive?
Galápagos tortoises lead an uncomplicated life, grazing on grass, leaves, and cactus, basking in the sun, and resting for nearly 16 hours per day. A slow metabolism and an ability to store large amounts of water mean they can survive up to a year without eating or drinking.
What climate does a Galapagos tortoise live in?
The tortoises live in muddy puddles and wallow, preferably in sunny areas. Some may be found at rest under large overhanging rocks. When it is the hot and dry season, these animals tend to go to the cooler highlands, and in the rainy season, they return to the lowlands.
Can you ride a Galapagos tortoise?
Most tortoises grow to be very large, some getting to be 500 pounds in weight. Even though they are strong, they should never be used as pack animals. They should never be ridden on, even by small kids.
Can Galapagos tortoise swim?
Galapagos tortoises can’t swim but they can float due to an extra layer of blubber. You can visit and touch our tortoises at 2pm each day during the summer.
Why might the Galapagos Islands be considered a biodiversity hotspot?
The Galapagos Islands are so biodiverse because of the many different habitat zones that can be found across the Islands. There are coral reefs, highland forests, sand dunes and scrubland, and the changing habitats from island to island. Species diversity is only one piece of the biodiversity puzzle.
Are Galapagos tortoise endangered?
All of the Galapagos giant tortoise species alive today are under threat and are on the IUCN Red List – they range from Vulnerable to Critically Endangered. One of them, the Eastern Santa Cruz giant tortoise (Chelonoidis donfaustoi) was, just last year, found to be Critically Endangered.
How fast can a Galapagos tortoise run?

| length | weight | top speed (walking) |
|---|---|---|

What did Darwin discover about Galapagos tortoises?
Darwin noticed that different tortoise species lived on islands with different environments. He realized that the tortoises had traits that allowed them to live in their particular environments. For example, tortoises that ate plants near the ground had rounded shells and shorter necks.
What does a Galapagos tortoise look like?
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.
How does a Galapagos tortoise defend itself?
Tortoises have the ability to use their tough claws and strong legs to dig into the ground and create burrows, which protect them from both predators, as well as hot and cold climate conditions. A tortoise may dig several burrows in its territory as a means of escaping weather conditions or predators as needed.
Why is one tortoise born with a longer neck?
Tortoises occurring on more arid islands had to stretch their necks to reach branches of cactus and other vegetation.In a single clutch of eggs there will be some hatchlings, which, because of their genetic constitution, will develop longer necks than others.
What distinguishes Galapagos tortoises from island to island?
NARRATOR: The Galapagos Islands take their name from the giant land tortoises found there. Tortoises from different islands can be identified by the shape of their shells, which appear to have evolved into two main types with slight variations.
