There are over 1,000 animal species; notable among them are the seabirds Cory's shearwater ("Calonectris diomedea"), various cormorants ("Phalacrocorax"), the common swift ("Apus apus"), and the Manx shearwater ("Puffinus puffinus") as well as numerous reptiles, such as the endemic Lilford's wall lizard ("Podarcis lilfordi") found on several of the islets of the archipelago.

Alternatively (Austin 1996, Austin "et al." 2004), it
