Anguis veronensis, commonly known as the Italian slow worm, is a European lizard species in the family Anguidae. The slow worm is distributed throughout Italy and in southeastern part of France. [1]
A. veronensis got its first scientific description in 1818, when it was described by Italian naturalist Ciro Polinni, and named after the Italian city Verona, where specimens were found. [2] [3] The synonymous species name Anguis cinerea (cinereus) is derived from the Latin word cinereus meaning ash-grey, even though typical gray colour is a common feature of the whole genus Anguis, especially the similar common slow worm, Anguis fragilis . [1]
In the past, slow worms from the Italian Peninsula were not distinguished from other European slow worms; they were usually perceived as conspecifics of Anguis fragilis . [4] A relatively long independent evolutionary history and distinct identity of both morphological and genetic features [4] led to the species resurrection in 2013 under the synonymous scientific name Anguis cinerea. [1] [4] Following the rules of International Code of Zoological Nomenclature about priority naming the slow worm was renamed to the oldest available name for the same taxon, Anguis veronensis. [1]
Distinguishing the Italian slow worm from other genetically deeply divergent species of genus Anguis can be done by performing genetic analysis, since species are closely morphologically similar and thus poorly separable. [1] [4] [5] Analyses of the morphological comparison showed that A. veronensis differs from A. fragilis in relative tail length (A. veronensis has longer tail in both sexes), subcaudal scales (A. veronensis has more subcaudal scales in both sexes) and head morphology (A. veronensis has relatively more robust head). Differences in log-linear analysis of both lizard's colouration were negligible, the same goes for insufficient variation in the external ear opening presence. [4]
For now, this anguid species has been observed only in Italy and some parts of France. Some experts hypothesize the slow worm's remotest area of distribution also includes southern parts of Switzerland. [4] [6] The species' main territories are located on the Italian Peninsula, with animals populating the whole peninsula but its southeastern parts. The Italian slow worm is more common in northern Italy, while populations in southern parts of the country are smaller. [4]
In north and northeastern Italy, as well as in Slovenia (only hybrids found [7] ), the Italian slow worm sometimes comes in contact with the common slow worm, resulting in occasional hybridization. [4] [8] Anguis veronensis inhabits exclusively the far southeastern mainland France, region Provence-Alpes-Côte d'Azur. [4] The species' presence has also been confirmed on the Mediterranean island Ile Sainte-Marguerite, with animals being genetically related to mainland slow worms of Provence-Alpes-Côte d'Azur. [8]
The northern populations' common habitats include various forest-steppe, steppe and ruderal areas, with some animals inhabiting urban surfaces. Slow worms of central and southern regions of Italy usually inhabit less diverse collection of habitats; borders of oak and beech forests are the most common, followed by sand dunes of Mediterranean characteristic maquis shrubland. Animals are known to live in altitudes ranging from sea level to more than 2.000 above in the Alps. [4]
Majority of individuals can be described as primarily diurnal (active at daytime) and occasionally crepuscular (active at twilight), while Mediterranean slow worms are mostly crepuscular and sometimes nocturnal (active at nighttime). [4]
The grey heron is a long-legged wading bird of the heron family, Ardeidae, native throughout temperate Europe and Asia, and also parts of Africa. It is resident in much of its range, but some populations from the more northern parts migrate southwards in autumn. A bird of wetland areas, it can be seen around lakes, rivers, ponds, marshes and on the sea coast. It feeds mostly on aquatic creatures which it catches after standing stationary beside or in the water, or stalking its prey through the shallows.
Anguidae refers to a large and diverse family of lizards native to the Northern Hemisphere. Common characteristics of this group include a reduced supratemporal arch, striations on the medial faces of tooth crowns, osteoderms, and a lateral fold in the skin of most taxa. The group is divided into two living subfamilies, the legless Anguinae, which contains slow worms and glass lizards, among others, found across the Northern Hemisphere, and Gerrhonotinae, which contains the alligator lizards, native to North and Central America. The family Diploglossidae was also formerly included. The family contains about 87 species in 8 genera.
Slowworms are a small genus (Anguis) of snake-like legless lizards in the family Anguidae. The genus has several living species, including the common slowworm, the eastern slowworm, the Greek slowworm, the Peloponnese slowworm, and the Italian slowworm. There are also known fossil species.
The red-backed salamander is a small, hardy woodland salamander species in the family Plethodontidae. It is also known as the redback salamander, eastern red-backed salamander, or the northern red-backed salamander to distinguish it from the southern red-backed salamander. The species inhabits wooded slopes in eastern North America, west to Missouri, south to North Carolina, and north from southern Quebec and the Maritime provinces in Canada to Minnesota. It is one of 56 species in the genus Plethodon. Red-backed salamanders are notable for their color polymorphism and primarily display two color morph varieties, which differ in physiology and anti-predator behavior.
The slowworm is a legless lizard native to western Eurasia. It is also called a deaf adder,slow worm, blindworm, or regionally, a long-cripple and hazelworm. The "blind" in blindworm refers to the lizard's small eyes, similar to a blindsnake.
Tarentola mauritanica, known as the common wall gecko, is a species of gecko (Gekkota) native to the western Mediterranean area of North Africa and Europe. It has been introduced to Madeira and Balearic Islands, and the Americas. A nocturnal animal with a predominantly insectivorous diet, it is commonly observed on walls in urban environments in warm coastal areas; it can be found further inland, especially in Spain where it has a tradition of cohabitation with humans as an insect hunter. A robust species, up to 15 centimetres (5.9 in) long, its tubercules are enlarged and give the species a spiny armoured appearance.
Anguinae is a subfamily of legless lizards in the family Anguidae, commonly called glass lizards, glass snakes or slow worms. The first two names come from the fact their tails easily break or snap off. Members of Anguinae are native to North America, Europe, Asia, and North Africa.
Spirometra erinaceieuropaei is a parasitic tapeworm that infects domestic animals and humans. The medical term for this infection in humans and other animals is sparganosis. Morphologically, these worms are similar to other worms in the genus Spirometra. They have a long body consisting of three sections: the scolex, the neck, and the strobilia. They have a complex life cycle that consists of three hosts, and can live in varying environments and bodily tissues. Humans can contract this parasite in three main ways. Historically, humans are considered a paratenic host; however, the first case of an adult S. erinaceieuropaei infection in humans was reported in 2017. Spirometra tapeworms exist worldwide and infection is common in animals, but S. erinaceieuropaei infections are rare in humans. Treatment for infection typically includes surgical removal and anti-worm medication.
The Iberian worm lizard, Mediterranean worm lizard, or European worm lizard is a species of reptile in the family Blanidae of the clade Amphisbaenia. The Iberian worm lizard is locally known as cobra-cega (Portuguese), culebrilla ciega (Spanish), and colobreta cega (Catalan), all meaning "blind snake". Recent studies into the mitochondrial and nuclear genomic data of 47 isolated B. cinereus populations show rather large sequence divergence between two apparent clades, leading some researchers to call for a division of the Iberian worm lizard into two species. While little is known of B. cinereus in comparison with some other reptile species, new insight is growing about this primitive, ancestral reptile.
The fauna of Italy comprises all the animal species inhabiting the territory of the Italian Republic and its surrounding waters. Italy has one of the highest levels of faunal biodiversity in Europe, with over 57,000 species recorded, representing more than a third of all European fauna. 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.
In the 10th edition of Systema Naturae, Carl Linnaeus described the Amphibia as:
Animals that are distinguished by a body cold and generally naked; stern and expressive countenance; harsh voice; mostly lurid color; filthy odor; a few are furnished with a horrid poison; all have cartilaginous bones, slow circulation, exquisite sight and hearing, large pulmonary vessels, lobate liver, oblong thick stomach, and cystic, hepatic, and pancreatic ducts: they are deficient in diaphragm, do not transpire (sweat), can live a long time without food, are tenatious of life, and have the power of reproducing parts which have been destroyed or lost; some undergo a metamorphosis; some cast (shed) their skin; some appear to live promiscuously on land or in the water, and some are torpid during the winter.
Anguis colchica, the eastern slow worm, is a species of lizard in the family Anguidae found in eastern and northern Europe and Asia. It is easily confused with the common slow worm, due to their physical similarities, and the proximity of their distribution.
