Pupillidae
Pupillidae is a family of mostly minute, air-breathing, land snails, terrestrial pulmonate gastropod mollusks or micromollusks in the superfamily Pupilloidea. MolluscaBase eds. (2021). MolluscaBase. Pupillidae W. Turton, 1831. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=426389 on 2021-07-25 This family has two subfamilies (according to the taxonomy of the Gastropoda by Bouchet & Rocroi, 2005).: Pupillinae W. Turton, 1831 and Pupoidinae Iredale, 1940. Distribution ''Pupoides marginatus'' is endemic to Cuba. The type genus, ''Pupilla'', in direct contrast, has numerous living and extinct species found in Europe, Northern Africa, North America and South-East Asia. Anatomy In this family, the number of haploid chromosomes lies between 26 and 30 (according to the values in this table).Barker G.

Vertiginidae
Vertiginidae, common name the whorl snails, is a family of minute, air-breathing land snails, terrestrial pulmonate gastropod molluscs or micromollusks in the superfamily Pupilloidea. Distribution The distribution of the Vertiginidae is in the Northern Hemisphere: North America (60 species), Eurasia (30 species), North and central Africa (3-5 species). That gives a total of approximately 93-95 species. Ecology Snails in this family inhabit habitats ranging from forests to semi-open and open habitats with various different kinds of substrate cover, vegetation and humidity. They feed on microflora - bacteria and fungi - growing on dead and living plants. Taxonomy The following three subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005): * Subfamily Vertigininae Fitzinger, 1833 ** Tribe Vertiginini Fitzinger, 1833 ** Tribe Truncatellinini Steenberg, 1925 - synonyms: Truncatellininae; Columellinae Schileyko, 1998 - raised in 2016 to family level Truncatellin ...

Animalia
Animals are multicellular, eukaryotic organisms in the biological kingdom Animalia. With few exceptions, animals consume organic material, breathe oxygen, are able to move, can reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of cells, the blastula, during embryonic development. Over 1.5 million living animal species have been described—of which around 1 million are insects—but it has been estimated there are over 7 million animal species in total. Animals range in length from to . They have complex interactions with each other and their environments, forming intricate food webs. The scientific study of animals is known as zoology. Most living animal species are in Bilateria, a clade whose members have a bilaterally symmetric body plan. The Bilateria include the protostomes, containing animals such as nematodes, arthropods, flatworms, annelids and molluscs, and the deuterostomes, containing the echinode ...

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.
