Rare amphibians, found only on the island, are the Sardinian brook salamander, brown cave salamander, imperial cave salamander, Monte Albo cave salamander, Supramonte cave salamander and Sarrabus cave salamander ("Speleomantes sarrabusensis"); the Sardinian tree frog is also found in Corsica and in the Tuscan Archipelago. Among reptiles worthy of note are Bedriaga's rock lizard, the Tyrrhenian wall lizard and Fitzinger's algyroides, endemic species of Sardinia and Corsica. The island is inhabited by terrestrial tortoises and sea turtles like Hermann's tortoise, the spur-thighed tortoise, marginated tortoise ("Testudo marginata sarda"), Nabeul tortoise, loggerhead sea turtle and green sea turtle. A new arachnid species, endemic to the island, has been recently found: the Nuragic spider.
