Key Facts & Information

Background

• Tortoise is the word referred to slow, terrestrial turtles. This was determined by the American Society of Ichthyologists and Herpetologists.
• Tortoises and turtles have existed since 300 million years ago.
• They inhabit places with a semi-arid climate.

Physical Characteristics

• A tortoise’s shell is not a single shell, but rather a composition of 60 bony plates.
• The top part is called a carapace and the underside is called a plastron.
• Both sides are joined by a bridge.
• The top carapace has scales on it called scutes.
• Scutes protect the shell plates from getting injured.
• Tortoises can hide their head, feet, and tail in their shell.
• A tortoise has a collarbone, ribs, and a spine inside its shell.
• Their shells are very sensitive.
• Tortoises are able to feel anything that touches their shells, even if you touch it very softly.
• You can tell the age of a tortoise by the rings around its scutes.
• The color of a tortoise’s shell is telling to its place of origin.
• Tortoises with light-colored shells come from warmer places.
• The sulcata, for instance, has a light tan shell and it comes from the Sahara Desert.
• Tortoises have no teeth so they chew their food using ridges in their tough mouths.
• Tortoises have no ears, but they have two tiny holes on the sides of their heads.
• On the roof of their mouths is what is called the Jacobson’s organ.
• The Jacobson’s organ is a vomeronasal organ that allows tortoises to have a sharp sense of smell.
• Tortoises can smell even the faintest of scents.
• They circulate air that passes through their nose by pumping their throats.
• Tortoises are sensitive to bright colors.
• A tortoise’s feet can draw heat from the ground.

Other Characteristics

• Although tortoises can’t swim, they can hold their breath underwater for long periods of time because they’re able to tolerate carbon dioxide.
• Tortoises are cold-blooded and get warmth from their environment. This is why they like sunbathing.
• Tortoises are diurnal, meaning they’re active in the day and asleep at night.
• Tortoises are mostly herbivorous.
• Not all turtles are tortoises.
• Tortoises are mainly terrestrial while turtles are mostly water-dwelling.
• The main physical difference of turtles and tortoises are their feet and shells.
• Tortoises have short, thick feet like those of an elephant’s while turtles have webbed feet for swimming.
• A tortoise’s shell is heavier and more rounded while a turtle’s shell is lighter and flat.
• Tortoises are often loners.
• Tortoises are experts at getting all the water and nutrients they need from what they eat.
• Their hindgut system separates water from waste, which is handy when water is scarce and they need to rely on water from their waste.
• A tortoise’s sex can only be seen when it reaches a certain size.
• However, there are other ways to tell if a tortoise is male or female: by their shells and by their tails.
• Females generally have flatter plastrons and males tend to have longer tails.
• Females can lay eggs even without a male partner to fertilize them.

Species

• The largest tortoise species is the Galapagos tortoise which can weigh up to 440 pounds and grow up to 1.2 meters long.
• The Aldabra giant tortoise, found in the Aldabra atoll in Seychelles, is one of the largest tortoises in the world.

• The lifespan of a tortoise ranges from 90 to 250 years.
• Most tortoises hibernate in the winter.
• Tortoises hide in their shells when they’re startled.
• Tortoises exhibit sexual dimorphism, meaning males and females are distinctly different from each other in terms of appearance.
• Females are typically larger in size than males.
• Female tortoises lay up to 30 eggs at a time.
• Females leave their eggs in deep burrows that they dig and let the eggs incubate for 90 to 120 days.
• Males try to get the attention of females for mating by ramming their shells.
• Females can store a male’s sperm for up to three or four years until they use it to fertilize their eggs.
• It is not only the tortoise’s shell that is affected by temperature but also the tortoise’s sex.
• In warmer climates, there are more female offspring.

Tortoise Trivia

• The tortoise is the symbol of the Greek god Hermes.
• Charles Darwin once had a pet Galapagos tortoise named Harriet.
