Bostrycapulus Calyptraeiformis
''Bostrycapulus'', commonly known as the spiny slipper snails, is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae, the slipper snails, cup-and-saucer snails and hat snails. Before 2005, the snails in this genus were all thought to belong to one species, which was known as '' Crepidula aculeata'', the spiny slipper snail.Collin R. (2005). "Development, phylogeny, and taxonomy of'' Bostrycapulus'' (Caenogastropoda: Calyptraeidae), an ancient cryptic radiation". '' Zoological Journal of the Linnean Society'' 144(1): 75-101. . However, morphological and DNA sequence data show that the spiny slipper snails are a monophyletic group that is more closely related to '' Crepipatella'' than it is to ''Crepidula''. Taxonomy Taxonomic history All of the species within the genus'' Bostrycapulus'' were previously assigned to a single species, '' Crepidula aculeata''.

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 ...

Crepipatella
''Crepipatella'' is a genus of sea snails, marine gastropod mollusks in the family Calyptraeidae, the slipper snails and cup-and-saucer snails. MolluscaBase eds. (2020). MolluscaBase. Crepipatella Lesson, 1831. Accessed through: World Register of Marine Species at: http://www.marinespecies.org/aphia.php?p=taxdetails&id=234136 on 2020-09-26 The snails in this genus were formerly all thought to belong to the genus ''Crepidula'', but DNA sequence data show that they are a separate genus. A recent revision of the South American species has led to some significant taxonomic changes, as well as the addition of a new species - Crepipatella occulta Veliz et al. 2012. Species Species within the genus ''Crepipatella'' include: * ''Crepipatella capensis'' (Quoy and Gaimard, 1832–33) This species is known from the upwelling area of South Africa around Cape Town. These animals have direct development where embryonic nutrition is provided by nurse embryos (termed adelphophagy). ''C. c ...

Clade
A clade (), also known as a monophyletic group or natural group, is a group of organisms that are monophyletic – that is, composed of a common ancestor and all its lineal descendants – on a phylogenetic tree. Rather than the English term, the equivalent Latin term ''cladus'' (plural ''cladi'') is often used in taxonomical literature. The common ancestor may be an individual, a population, or a species (extinct or extant). Clades are nested, one in another, as each branch in turn splits into smaller branches. These splits reflect evolutionary history as populations diverged and evolved independently. Clades are termed monophyletic (Greek: "one clan") groups. Over the last few decades, the cladistic approach has revolutionized biological classification and revealed surprising evolutionary relationships among organisms. Increasingly, taxonomists try to avoid naming taxa that are not clades; that is, taxa that are not monophyletic. Some of the relationships between organisms ...

Monophyletic
In cladistics for a group of organisms, monophyly is the condition of being a clade—that is, a group of taxa composed only of a common ancestor (or more precisely an ancestral population) and all of its lineal descendants. Monophyletic groups are typically characterised by shared derived characteristics ( synapomorphies), which distinguish organisms in the clade from other organisms. An equivalent term is holophyly. The word "mono-phyly" means "one-tribe" in Greek. Monophyly is contrasted with paraphyly and polyphyly as shown in the second diagram. A ''paraphyletic group'' consists of all of the descendants of a common ancestor minus one or more monophyletic groups. A '' polyphyletic group'' is characterized by convergent features or habits of scientific interest (for example, night-active primates, fruit trees, aquatic insects). The features by which a polyphyletic group is differentiated from others are not inherited from a common ancestor. These definitions have tak ...
