The fauna of Italy comprises all the animal species inhabiting the territory of the Italian Republic and its surrounding waters. Italy has probably the highest level of faunal biodiversity in Europe, with over 57,000 species recorded, representing more than a third of all European fauna.[4] This is due to various factors. The Italian peninsula is in the centre of the Mediterranean Sea, forming a corridor between central Europe and North Africa, and it has 8,000 km (5,000 mi) of coastline. Italy also receives species from the Balkans, Eurasia, and the Middle East. Italy's varied geological structure, including the Alps and the Apennines, Central Italian woodlands, and Southern Italian Garigue and Maquis shrubland, also contribute to high climate and habitat diversity.
The fauna of Italy includes 4,777 endemic animal species, which include the Sardinian long-eared bat, Sardinian red deer, spectacled salamander, brown cave salamander, Italian newt, Italian frog, Apennine yellow-bellied toad, Italian wall lizard, Aeolian wall lizard, Sicilian wall lizard, Italian Aesculapian snake, and Sicilian pond turtle. In Italy, there are 119 mammals species, 550 bird species, 69 reptile species, 39 amphibian species, 623 fish species and 56,213 invertebrate species, of which 37,303 insect species.
Italy is probably the richest European country in both plant and animal biodiversity, with a population very rich in endemic forms.[5] It has the highest number and density of both animal and plant species within the European Union.[6] During the Pleistocene glaciations, the Italian territory remained largely free of ice, which allowed the flora and fauna to survive, something that did not happen in the central-northern areas of the continent, and the retreat of the great glaciers has left glacial relict fauna in some mountain locations.[7]
The Italian territory extends over about 10° of latitude, therefore, while remaining in the context of temperate climates without extremes of heat, cold or aridity, the climatic difference between the north and the south of the country is not at all negligible, going from the nival climates of the Alpine peaks to the cool semi-continental temperate climate of the Po Valley, to the Mediterranean climate of the central-southern coasts and the islands.[8] Italy is predominantly hilly and mountainous in nature of the territory, which has caused a proliferation of ecological niches, close in space but very diversified.[9]

Further information: Geography of Italy and Climate of Italy |
Italy consists of a 1,000 km (620 miles) long peninsula extending out into the central Mediterranean, together with a number of islands to the south and west. The Apennines run north-south through the peninsula connecting the Alps in the north to Etna and the Peloritani mountains in Sicily in the south. The geology is diverse.
Northern Italy is dominated by the Alps and an extensive valley of the Po river which is extensively agricultural and industrialised. Central Italy includes the regions of Tuscany, Umbria, Marche and Lazio. It is dominated by the Apennines, from which a few major rivers flow. There are few natural plains. A process of land reclamation has replaced the coastal swamps and marshes with agricultural land.
Southern Italy includes the regions of Abruzzo, Molise, Apulia, Basilicata and Campania. Agriculture and industry are less developed. The main islands are Sicily, Sardinia and the Aeolian Islands.
Because of the length of the Italian peninsula and the mostly mountainous hinterland, the climate of Italy is highly diverse. In most of the inland northern and central regions, the climate ranges from humid subtropical to humid continental and oceanic. In particular, the climate of the Po Valley geographical region is mostly continental, with harsh winters and hot summers.[10][11] The coastal areas of Liguria, Tuscany and most of the South generally fit the Mediterranean climate stereotype (Köppen climate classification). Each region has a distinct fauna.

Further information: List of ecoregions in Italy |
An ecoregion is an ecologically and geographically defined area with characteristic species. Most of the Italian territory is included in the Mediterranean Basin. Important Italian terrestrial ecoregions include the Illyrian deciduous forests, the Italian sclerophyllous and semi-deciduous forests, the South Apennine mixed montane forests, the Tyrrhenian-Adriatic sclerophyllous and mixed forests, Apennine deciduous montane forests, the Dinaric Mountains mixed forests and the Po Basin mixed forests. There are also many cave systems significant for biodiversity.[12]
The Checklist of the Species of the Italian Fauna includes 4,777 endemic animal species in Italy.[13]
Unique mammals include the Corsican hare, the Sardinian long-eared bat, the Apennine shrew, the Udine shrew the Calabria pine vole, and the Sardinian deer.
Endemic amphibians and reptiles include the spectacled salamander, the Sardinian cave salamander, the Italian cave salamander, the Monte Albo cave salamander, the Sardinian brook newt, the Italian newt, the Italian frog, the Apennine yellow-bellied toad, the Sicilian green toad, the Aeolian wall lizard, the Sicilian wall lizard, the Italian Aesculapian snake, and the Sicilian pond turtle (Emys trinacris).
Endemic fishes include the Bergatino loach, the Italian barbel, the brook chub, the Arno goby, the Garda carp, the carpione del Fibreno, and the Timavo sculpin. Endemic birds include the Italian sparrow. There are 288 endemic species of lepidopterans in Italy.[14] A notable species is the European owl moth found only in Southern Italy.

Main article: List of mammals of Italy |
There are 119 species of mammals in Italy.[15] Some of the species are Alpine marmot, forest dormouse, Etruscan shrew (the smallest mammal in the world), European snow vole, and Schreiber's long-fingered bat. Notable large mammals are the Eurasian lynx, Italian wolf, Marsican brown bear, Pyrenean chamois, Alpine ibex, common genet, fallow deer, mouflon, rough-toothed dolphin, crested porcupine, and Mediterranean monk seal.

Italy has recorded 550 bird species.[17] Notable birds are the hoopoe, roller, white-backed woodpecker, black woodpecker, European green woodpecker, Alpine chough, snow finch, rock partridge, Bonelli's eagle, goshawk, eagle owl, lammergeier, Egyptian vulture, griffon vulture, collared pratincole, glossy ibis, spoonbill, Allen's gallinule, great bustard, trumpeter finch, rosy starling, great spotted cuckoo, woodchat shrike, bluethroat, and Eurasian nightjar.
Italy is an important route for trans-Saharan bird migrants because it is a natural bridge connecting continental Europe to Africa across the Mediterranean. Migratory birds with a low wing loading, such as stork, European honey buzzard, black kite, marsh harrier, kestrel, and hobby, depend on thermals and updrafts for soaring to cross the Mediterranean in spring. Although the majority of these birds enter Europe via the Bosphorus or Straits of Gibraltar, large numbers leave at Cap Bon in Tunisia and enter Europe via the Aeolian Islands and the Straits of Messina to Calabria. Most of these birds breed in central and northern Europe. The birds return to Africa in autumn by the same route.

Main article: Marine life of the Strait of Messina |
The Tyrrhenian and Ionian meet in Straits of Messina, generating powerful currents and strong turbulence, aggravated by the abrupt changes of sea bottom topography in the vicinity of the town of Messina. As a consequence, many species known as rare in the Mediterranean are found in large numbers in the straits. It is common to find deep species at the surface and vice versa, or open-sea species along the coast. The upwelling water drags abyssal species to the surface and sometimes strands them on the shore. Made famous in the nineteenth century by the zoologists Nicholas Miklouho-Maclay and Anton Dohrn, the straits have an extraordinary abundance and structure of planktonic, benthic, and nektonic communities.
The Italian fauna is rich in introduced species. Many introductions date from the time of the Roman Empire, such as the common carp.
Examples of more recent—and sometimes unwelcome—arrivals are the Asian tiger mosquito from Southeast Asia, the citrus long-horned beetle from China, the citrus pest cottony cushion scale, the pumpkinseed fish, the mosquitofish, the Louisiana crayfish, the zebra mussel, the strawberry finch, the Eastern grey squirrel, Finlayson's squirrel, and the coypu. Two introduced parrot species, the monk parakeet and the rose-ringed parakeet, are found in city parks.

Main article: List of Lessepsian migrants |
Since the construction of the Suez Canal in 1869, invasive marine species originating from the Red Sea have become a major component of the Mediterranean ecosystem. Known as the Lessepsian migration, the introduced species have caused serious impacts on the Mediterranean ecology, endangering many local and endemic Mediterranean species. About 300 species native to the Red Sea have already been identified in the Mediterranean Sea, and there are probably others yet unidentified.
