Home > Turtle Database > Cylindraspis inepta (Saddle-backed Mauritius Giant Tortoise)
Cylindraspis inepta was a large, extinct species of tortoise that once inhabited the islands of Mauritius. Known for its slow movements and distinctive shell, this species played an essential role in its ecosystem before its extinction due to human activity and introduced species.
Scientific Classification
- Kingdom: Animalia
- Phylum: Chordata
- Class: Reptilia
- Order: Testudines
- Family: Testudinidae
- Genus: Cylindraspis
- Species: C. inepta
Common Names
- Saddle-backed Mauritius Giant Tortoise
Identification
Description
Cylindraspis inepta had a large, dome-shaped carapace that was relatively smooth. It had strong, columnar legs, suited for moving slowly through dense vegetation. The tortoise could reach a considerable size, with an elongated neck and head.
Sexual Dimorphism
There is limited information on sexual dimorphism in this species, but like many tortoises, males were likely larger and had concave plastrons.
Native Origin and Distribution
Geographical Range
This tortoise was endemic to the islands of Mauritius in the Indian Ocean, where it thrived in the forests and grasslands.
Preferred Habitat
Cylindraspis inepta preferred forested areas and grassy lowlands, where it could feed on the abundant vegetation. The climate of Mauritius offered a suitable environment for this species’ slow lifestyle.
Behavior
Feeding Habits
This species was herbivorous, primarily feeding on grasses, shrubs, and low-lying plants. It helped in seed dispersal, contributing to the health of the local ecosystem.
Predators
Before the arrival of humans and their introduced animals, Cylindraspis inepta had few natural predators. However, the introduction of invasive species like rats, pigs, and cats led to their downfall.
Reproduction
Breeding Season
Little is known about the specific breeding season of Cylindraspis inepta, but tortoises in similar climates typically breed during warmer seasons.
Reproductive Method
Females laid eggs in shallow nests dug into the ground, with hatchlings emerging after a lengthy incubation period.
Conservation
Extinction Status
Cylindraspis inepta is extinct. It disappeared in the early 18th century, primarily due to human exploitation and the introduction of invasive species.
Threats
The primary threats were overhunting by humans for food and habitat destruction. Invasive species also contributed to egg predation and competition for resources.
Conservation Measures
Unfortunately, no conservation measures were in place at the time to protect Cylindraspis inepta before its extinction.
Economic Importance
While this species had no major economic importance, it was hunted for food by early settlers and sailors passing through Mauritius.
Interesting Facts
- Cylindraspis inepta played a significant role in maintaining the balance of the Mauritian ecosystem through grazing and seed dispersal.
- The species was named “inepta” due to its slow and lumbering movements.
