Information: - Stylommatophora is a taxon of air-breathing land snails and slugs, terrestrial pulmonate gastropod molluscs. This taxon is considered to be a clade. It used to be regarded as an infraorder (also sometimes was considered to be an order). This taxon includes the majority of land snails and slugs. - Bradybaenidae is a taxonomic family of medium - sized to small land snails , terrestrial pulmonate gastropod mollusks in the superfamily Helicoidea . These snails are found mainly in Asia , with only one species occurring in Northwestern Europe : Fruticicola fruticum . The name of the family and the genus Bradybaena is derived from the Greek words bradus ( = slow ) and baino ( = walk ) , meaning '' slow walker '' . Molecular phylogenetic studies from 2007 showed that bradybaenids are closely related with the Camaenidae , which are currently recognized as a distinct family . In these studies both Bradybaenidae and Camaenidae are mutually polyphyletic , together forming a monophyletic group , however . This finding suggests that the distinction of both families as based essentially on the absence ( Camaenidae ) or presence ( Bardybaenidae ) of a diverticulum , is arbitrary . This anatomical structure was apparently lost ( or was gained ) in several groups in convergence and is therefore not suitable for the delimitation of natural groups . As a result , the Bradybaenidae being the younger taxon are likely to represent a junior synonym of the Camaenidae . - Helicoidea is a taxonomic superfamily of air-breathing land snails, terrestrial pulmonate gastropod mollusks in the clade Stylommatophora. - Snail is a common name that is applied most often to land snails, terrestrial pulmonate gastropod molluscs. However, the common name "snail" is also applied to most of the members of the molluscan class Gastropoda that have a coiled shell that is large enough for the animal to retract completely into. When the word "snail" is used in this most general sense, it includes not just land snails but also thousands of species of sea snails and freshwater snails. Occasionally a few other molluscs that are not actually gastropods, such as the Monoplacophora, which superficially resemble small limpets, may also informally be referred to as "snails". After reading the paragraphs above, we are interested in knowing the entity with which 'bradybaenidae' exhibits the relationship of 'parent taxon'. Find the answer from the choices below.
