Tortoise
A tortoise is a land-dwelling reptile in the family Testudinidae, within the order Testudines.
A tortoise is a land-dwelling reptile in the family Testudinidae, within the order Testudines. Tortoises are distinguished by their heavy, often domed shells and adapted legs for walking on land. While not native to Canada as wild reptiles, they are familiar to Canadian readers through zoological collections, the pet trade, and conservation education.
Classification
Tortoises belong to the reptile order Testudines and the family Testudinidae. Historically, the word tortoise was sometimes used for any terrestrial turtle, but it now usually refers specifically to Testudinidae.
Physical characteristics
Tortoises typically have a hard shell, a high-domed carapace, and sturdy limbs suited for walking on land. Compared with aquatic turtles, they generally have heavier bodies and less webbing between the toes.
Habitat and distribution
Tortoises live in a wide range of terrestrial habitats, including deserts, grasslands, and tropical or subtropical environments. They are found on all major land masses except Antarctica and Australia.
Diet and behaviour
Most tortoises are herbivores, feeding on grasses, leaves, flowers, and other plant material. Many species are slow-moving and are known for long lifespans and low reproductive rates.
Conservation
Several tortoise species face pressure from habitat loss, hunting, and the wildlife trade. Conservation status varies widely across the group, with some species considered threatened or endangered.
Key facts
- Tortoises are reptiles in the family Testudinidae.
- All tortoises are turtles, but not all turtles are tortoises.
- They are adapted for life on land and have heavy shells.
- Tortoises occur on most continents, but not Antarctica or Australia.
- Some species are highly threatened, including critically endangered and endangered taxa.
Tortoises are not native to Canada as wild reptiles, but they are familiar to Canadian readers through zoological collections, the pet trade, conservation education, and comparisons with other turtles and terrapins.
