	All continents have land snails, they are especially prevalent everywhere in Eastern North America, where there are more than 500 native species. They live mostly in leaf litter of forests, old fields, and wetlands. They can also be found in more disturbed habitats such as active gardens and fields, river banks, suburbs, and even cities. The term ‘land snails’ includes snails and slugs, which have no obvious shell, they're shell is actually inside them.

	Most land snails feed upon a wide variety of organic material. But it is mainly consistent of green or dead herbaceous plants, rotting wood and fungi, bark and algae. They also consume empty snail shells, sap, animal scats and carcasses, and even rasp on limestone rock or cement [4].The radula (like in many mollusks,) has a rasping tongue as a mandible, they can use to ‘rasp’. It is full of horny teeth made of chitin and is used for scraping off particles of food from underneath [6].		Most land snails feed upon a wide variety of organic material.

	To further identify them, we can look at the order they are classified in, Stylommatophora. Stylommatophora includes air-breathing land snails and slugs. Snails in Stylommatophora have lost their gills, and have an air-breathing organ with a lung on its roof. The two things that all Stylommatophora share are a long pedal gland placed beneath a membrane and retractile tentacles. Their eyes can also be found on the tips of two long tentacles, in this case, the decollate snails eye stalks.

	==Habitat and Distribution==		==Habitat and Distribution==
	Decollate snails are native to North Africa and the Mediterranean Region. They were introduced into Southern California in the 1960s. They now occupy irrigated sites in Central and Southern California. They are considered introduced and not invasive, because they are non-native but do not seem to be causing harm. Because this snail is a burrowing species and the eggs and snails occur in topsoil, the snail can be spread easily by humans in plants and soil that are moved, leading to them being found in more states than California [3]. Currently, they are introduced in the United States, Bermuda and Mexico. It is widespread, but localized, in the Sun Belt from California east to Florida and north along the Atlantic coast to Pennsylvania [5]. As for their native habitats, In Europe they live in dry and open habitats, and prefer shady habitats in Portugal, between plants and under stones, or buried in the soil. They dislike sandy and loamy soils. In North Africa snails can be found up to 10 cm deep inside the soil, and under stones. Yet they are rarely found in the root systems of shrubs [1].

	While considered introduced in the US, some argue decollate snails may have an anthropogenic benefit here. Some people say they have value in controlling the brown garden snail as a pest in [[agriculture]], and this is considered to outweigh the decollate snail's ‘minor pest’ attributes in California. Although they are still only in cultivated habitats with frequent irrigation [5]. Although studies have shown that they are not consistently effective, introducing the decollate snail can reduce brown garden snail populations to insignificant levels in 4 to 10 years [3].

	Since these snails don't move far over their lifetime, they can be excellent indicators of site history and site conditions.
