Terrestrial Reptiles and Amphibians
In Tristan Da Cunha, a remote volcanic island in the South Atlantic Ocean, there are no native terrestrial reptiles and amphibians. The isolation of the island, combined with its harsh climate and limited resources, make it difficult for these types of animals to survive.
However, there have been some sightings of non-native species. For example, the Mediterranean House Gecko (Hemidactylus turcicus) has been introduced to Tristan Da Cunha and is now established on the island. This small lizard is able to survive in the island’s rocky terrain and can often be found hiding in crevices and under rocks.
Additionally, there have been reports of frogs on the island, although the exact species is unknown. It is believed that these frogs were unintentionally introduced to Tristan Da Cunha and are now occupying small pockets of suitable habitat.
| Species | Description |
|---|---|
| Mediterranean House Gecko (Hemidactylus turcicus) | A small lizard that can adapt to various habitats and is able to climb walls and ceilings. |
| Unknown Frog Species | Species of frog that has been unintentionally introduced to Tristan Da Cunha. |
It is important to note that the introduction of non-native species can have negative impacts on the delicate ecosystems of Tristan Da Cunha. These species can outcompete native organisms for resources and disrupt the balance of the ecosystem. Efforts are being made to monitor and manage the presence of non-native species on the island.
