Q:Information: - Cycloneritimorpha ( nerites and false - limpets ) is a clade of land snails , freshwater snails , and sea snails . These are gastropod molluscs within the larger clade Neritimorpha . 14 of the families in the clade are extant , and eight of the families are extinct . According to the Taxonomy of the Gastropoda ( Bouchet & Rocroi , 2005 ) , as well as the Cycloneritimorpha , the clade Neritimorpha also contains the ( entirely fossil ) clade Cyrtoneritimorpha , plus a number of other fossil families that are currently unassigned . The earliest evolutionary forms of Cycloneritimorpha show double visceral organs , double gills , and normally a double - chambered heart . - 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". - Ants are eusocial insects of the family Formicidae and, along with the related wasps and bees, belong to the order Hymenoptera. Ants evolved from wasp-like ancestors in the Cretaceous period, about 99 million years ago and diversified after the rise of flowering plants. More than 12,500 of an estimated total of 22,000 species have been classified. They are easily identified by their elbowed antennae and the distinctive node-like structure that forms their slender waists. - A clade (from , "klados", "branch") is a group of organisms that consists of a common ancestor and all its lineal descendants, and represents a single "branch" on the "tree of life". - Neritimorpha is a taxonomic grouping, an unranked clade of snails, gastropod mollusks. This grouping includes land snails, sea snails, some deepwater limpets, and also freshwater snails. This clade used to be known as the superorder Neritopsina. After reading the paragraphs above, we are interested in knowing the entity with which 'cycloneritimorpha' exhibits the relationship of 'taxon rank'. Find the answer from the choices below. Choices: - branch - class - family - group - order - species - superorder
