The site consists of a group of calcareous islands and islets which are characterized by rocky and eroded coasts, as well as of the surrounding sea area confined by the isobath of 50 m. The biggest islands of this group, Paxoi and Antipaxoi also show an interesting topography. Paxoi is the only island of this group which is permanently inhabited. The flora of the area consists of about 450 taxa. The majority of them,c. 65%, are typical mediterranean elements but 2 species, namely Centaurea paxorum and Limonium antipaxorum, are local endemics. The main natural vegetation type which dominates in the site seems to be evergreen shrubs or tree-like shrubs belonging to either Oleo-Ceratonion (Ceratonia siliqua, Olea europaea, Pistacia lentiscus, Calycotome villosa, Quercus coccifera etc.) or Quercion ilicis (Phyllirea media, Rhamnus alaternus, Pistacia terebinthus, Arbutus adrachne etc). Clusters of Mediterranean conifers (Juniperus phoenicea, Pinus halepensis and Cupressus sempervirens) are not uncommon within both the above mentioned vegetation types. Juniperus phoenicea and Pinus halepensis seem to be localized in the northwestern and southeastern part (islet Mogonisi) of Paxoi island respectively. In the rocky coasts, the vegetation zone is characterized by the presence of several plant species adapted to the corresponding conditions viz. Crithmum maritimum, Silene sedoides, Reichardia picroides, Daucus carota, Brassica cretica, Limonium antipaxorum, Centaurea antipaxorum etc. In the central part of Paxoi island, the degradation of the Oleo-Ceratonion and Quercus ilicis, due to the human activities of deforestation (fires, olive groves, vineyards, etc), is obvious and the secondary vegetation type of phrygana (Coridothymion) is observed.The site is a foraging area of marine turtles and hence it extents to the isobath of 50m. Marine habitats (subregion: NISOI PAXOI KAI ANTIPAXOI): In 2015, the site was extended 2nm off coast to comprise important and sensitive circalittoral and deep habitats. The total area now spans about 200km2 of seabed surface, frequently exceeding depths of 200m. The western coasts of the islands are steep-sloping and rather exposed to wave action, while the eastern coasts are more sheltered and milder sloping. Several islets, reefs and shoals add to the geographic and topographic complexity of the site. Cetaceans (subregion: NISOI PAXOI KAI ANTIPAXOI KAI EVRYTERH THALASSIA ZONI APO NOTIA KERKYRA EOS AKROTIRIO AGIOS THOMAS (PREVEZA)): The site consists of a group of calcareous islands and islets which are characterized by rocky and eroded coasts and of all their surrounding territorial sea area, including the waters around south Corfu and off the neighboring west mainland coasts. The vast majority of the site's sea area consists of shallow (<200 m) waters inhabited by both coastal dolphin species: bottlenose dolphin (Tursiops truncatus) and common dolphin (Delphinus delphis). In the west part of the site, west of Paxoi-Antipaxoi Islands, the depth increases rapidly offering appropriate habitat for slope and pelagic cetacean species. The striped dolphin (Stenella coeruleoalba), the Cuvier's beaked whale (Ziphius cavirostris) and the fin whale (Balaenoptera physalus) inhabit or cross this area. The Risso's dolphin (Grampus griseus) is also likely to cross the area according to strandings of this species that have occurred in the wider zone. However, it has not been recorded so far.
