Animals range in length from to . They have Ecology, complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology.

Succineidae
Succineidae are a family of small to medium-sized, air-breathing land snails (and slugs), terrestrial pulmonate gastropod molluscs in the superfamily Succineoidea.MolluscaBase eds. (2021). MolluscaBase. Succineidae Beck, 1837. Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=181585 on 2021-02-23 They are commonly called amber snails because their thin fragile shells are translucent and amber-colored. They usually live in damp habitats such as marshes. Succineidae is the only family in the superfamily Succineoidea. The soft parts of the animal appear to be too large for the shell.Janus, Horst, 1965. ‘’The young specialist looks at land and freshwater molluscs’’, Burke, London Anatomy In this family, the number of haploid chromosomes varies greatly. The most common totals are less than 10, and also lies between 21 and 25, but other values are also possible (according to the values in this table).Barker G. M ...

Mollusk
Mollusca is the second-largest phylum of invertebrate animals after the Arthropoda, the members of which are known as molluscs or mollusks (). Around 85,000 extant species of molluscs are recognized. The number of fossil species is estimated between 60,000 and 100,000 additional species. The proportion of undescribed species is very high. Many taxa remain poorly studied. Molluscs are the largest marine phylum, comprising about 23% of all the named marine organisms. Numerous molluscs also live in freshwater and terrestrial habitats. They are highly diverse, not just in size and anatomical structure, but also in behaviour and habitat. The phylum is typically divided into 7 or 8 taxonomic classes, of which two are entirely extinct. Cephalopod molluscs, such as squid, cuttlefish, and octopuses, are among the most neurologically advanced of all invertebrates—and either the giant squid or the colossal squid is the largest known invertebrate species.

Gastropod
The gastropods (), commonly known as snails and slugs, belong to a large taxonomic class of invertebrates within the phylum Mollusca called Gastropoda (). This class comprises snails and slugs from saltwater, from freshwater, and from land. There are many thousands of species of sea snails and slugs, as well as freshwater snails, freshwater limpets, and land snails and slugs. The class Gastropoda contains a vast total of named species, second only to the insects in overall number. The fossil history of this class goes back to the Late Cambrian. , 721 families of gastropods are known, of which 245 are extinct and appear only in the fossil record, while 476 are currently extant with or without a fossil record. Gastropoda (previously known as univalves and sometimes spelled "Gasteropoda") are a major part of the phylum Mollusca, and are the most highly diversified class in the phylum, with 65,000 to 80,000 living snail and slug species.

Pulmonate
Pulmonata or pulmonates, is an informal group (previously an order, and before that a subclass) of snails and slugs characterized by the ability to breathe air, by virtue of having a pallial lung instead of a gill, or gills. The group includes many land and freshwater families, and several marine families. The taxon Pulmonata as traditionally defined was found to be polyphyletic in a molecular study per Jörger ''et al.'', dating from 2010. Pulmonata are known from the Carboniferous Period to the present. Pulmonates have a single atrium and kidney, and a concentrated, symmetrical, nervous system. The mantle cavity is located on the right side of the body, and lacks gills, instead being converted into a vascularised lung. Most species have a shell, but no operculum, although the group does also include several shell-less slugs. Pulmonates are hermaphroditic, and some groups possess love darts.

Terrestrial Animal
Terrestrial animals are animals that live predominantly or entirely on land (e.g. cats, dogs, ants, spiders), as compared with aquatic animals, which live predominantly or entirely in the water (e.g. fish, lobsters, octopuses), and amphibians, which rely on a combination of aquatic and terrestrial habitats (e.g. frogs and newts). Some groups of insects are terrestrial, such as ants, butterflies, earwigs, cockroaches, grasshoppers and many others, while other groups are partially aquatic, such as mosquitoes and dragonflies, which pass their larval stages in water. Terrestrial animals tend to be more developed and intelligent than aquatic animals. Terrestrial classes The term "terrestrial" is typically applied to species that live primarily on the ground, in contrast to arboreal species, which live primarily in trees. There are other less common terms that apply to specific groups of terrestrial animals: *Saxicolous creatures are rock dwelling. "Saxicolous" is derived from t ...

Land Snail
A land snail is any of the numerous species of snail that live on land, as opposed to the sea snails and freshwater snails. ''Land snail'' is the common name for terrestrial gastropod mollusks that have shells (those without shells are known as slugs). However, it is not always easy to say which species are terrestrial, because some are more or less amphibious between land and fresh water, and others are relatively amphibious between land and salt water. Land snails are a polyphyletic group comprising at least ten independent evolutionary transitions to terrestrial life (the last common ancestor of all gastropods was marine). The majority of land snails are pulmonates that have a lung and breathe air. Most of the non-pulmonate land snails belong to lineages in the Caenogastropoda, and tend to have a gill and an operculum. The largest clade of land snails is the Cyclophoroidea, with more than 7,000 species. Many of these operculate land snails live in habitats or microhabitats ...

Ludwig Karl Georg Pfeiffer
Ludwig Karl Georg Pfeiffer, also known as Louis Pfeiffer (4 July 1805 – 2 October 1877), was a German physician, botany, botanist and conchology, conchologist. Early life, Education & Medical Career Louis Pfeiffer was born in Cassel, the eldest son of the jurist Burkhard Wilhelm Pfeiffer and his wife Louise (née Harnier). Pfeiffer received his primary education in the Friedrichsgymnasium Kassel, Cassel Lyceum, where he distinguished himself academically, and by the age of fifteen was already at the top of his class. In 1820, political tensions forced his father to relocate the family to Lübeck, but Louis continued to excel, reaching the top of his class there as well. At the age of sixteen, Pfeiffer entered into university to study medicine, first at the University of Göttingen, and finally at the University of Marburg, where he studied under such prominent scientists as Georg Wilhelm Franz Wenderoth and :de:Ernst Daniel August Bartels, Ernst Daniel August Bartels, graduating ...

Succinea
''Succinea'', common name the amber snails, is a large genus of small, air-breathing land snails, terrestrial pulmonate gastropod molluscs in the family Succineidae. MolluscaBase eds. (2021).

Accessed through: World Register of Marine Species at: http://marinespecies.org/aphia.php?p=taxdetails&id=181586 on 2021-02-23 The common name refers to the fact that live snails in this genus are translucent and similar to amber in appearance. Description The length of the shell ranges between 9.4 mm and 17 mm, the width between 6.8 mm and 11.5 mm. The dextrous, pointed ovoid shell consists of 3⅓ - 3½ whorls. It is thin-walled, glossy and translucent. The protoconch is very compact. The spire is short and consists mainly of a large, wide body whorl and an oval aperture with a sharp angle at the top. The deep sutures are prominent.The interior surface of the aperture is cream-colored or white. The shell is usually light brown, but may b ...
