Habitat and Distribution
The Mauritian giant skink was native to Mauritius and had specific habitat needs that defined its range and preferences. Understanding where it lived helps paint a clearer picture of its existence before extinction.
Geographic Range
The Mauritian giant skink was found exclusively on the island of Mauritius. This limited geographic range meant that the skink adapted to the unique conditions of the island’s ecosystem. Historically, it populated areas that lacked large terrestrial mammals, which allowed reptiles like it to thrive.
Unfortunately, due to habitat destruction and the introduction of predators like rats and cats, the skink’s population declined. It ultimately became extinct in the 17th century, likely between 1600 and 1700. In addition, its close relative, the Réunion giant skink, also faced similar challenges on nearby Réunion Island.
Habitat Preferences
The Mauritian giant skink preferred dry, open terrains where it could bask in the sun and hunt for insects. It was often found in scrublands and low vegetation, which provided shelter from predators. These areas allowed the skink to be active during the day, making it easier to forage for food.
The skink thrived in environments that offered warmth and safety. Unfortunately, changes to its habitat, spurred by human activity, played a significant role in its extinction. Conservation efforts for remaining species on Mauritius highlight the importance of preserving fragile ecosystems similar to the one the giant skink once inhabited.
