Animal
Animals are multicellular, eukaryotic organisms in the Kingdom (biology), biological kingdom Animalia. With few exceptions, animals Heterotroph, consume organic material, Cellular respiration#Aerobic respiration, breathe oxygen, are Motility, able to move, can Sexual reproduction, reproduce sexually, and go through an ontogenetic stage in which their body consists of a hollow sphere of Cell (biology), cells, the blastula, during Embryogenesis, embryonic development. Over 1.5 million Extant taxon, living animal species have been Species description, described—of which around 1 million are Insecta, insects—but it has been estimated there are over 7 million animal species in total. 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.

Mollusca
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.

Gastropoda
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.

Caenogastropoda
Caenogastropoda is a taxonomic clade, a large diverse group which are mostly sea snails and other marine gastropod mollusks, but also includes some freshwater snails and some land snails. The clade is the most diverse and ecologically successful of the gastropods. Caenogastropoda contains many families of shelled marine molluscs – including the periwinkles, cowries, wentletraps, moon snails, murexes, cone snails and turrids – and constitutes about 60% of all living gastropods. Biology The Caenogastropoda exhibit torsion, and thus are included in what was previously called the Streptoneura (meaning ''twisted nerves''), also known as Prosobranchia (meaning ''gills forward''). Specifically, they are characterized by having only a single auricle in the heart and a single pair of gill leaflets, and are equivalent to the Monotocardia or Pectinobranchia of older authors. Taxonomy The taxon Caenogastropoda was first established by Leslie Reginald Cox in 1960 ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Cerithioidea
The Cerithioidea is a superfamily of marine, brackish water and freshwater gastropod containing more than 200 genera. The Cerithoidea are included unassigned in the subclass Caenogastropoda. The original name of this superfamily was Cerithiacea, in keeping with common superfamily endings at the time. Ecology Cerithioidea is a very diverse superfamily. Its species can be found worldwide mainly in tropic and subtropic seas on rocky intertidal shores, seagrass beds and algal fronds, but also in estuarine and freshwater habitats. The freshwater species are found on all continents, except Antarctica. They are dominant members of mangrove forests, estuarine mudflats, fast-flowing rivers and placid lakes.Healy J. M. & Wells F.

Turritellidae
Turritellidae, common name the "tower shells" or "tower snails", is a taxonomic family of small to medium-sized sea snails, marine gastropod molluscs in the clade Sorbeoconcha. These snails are filter feeders. This method of feeding is somewhat unusual among gastropod mollusks, but is very common in bivalves. Shell description The shells of turritellid species have whorls that are more convex and an aperture which is more circular than it is in the auger shells which are similarly high-spired. The columella is curved and the thin operculum is horny. Anatomy of the soft parts These snails burrow into mud or sand. The foot is relatively small. Taxonomy The following five subfamilies were recognized in the taxonomy of Bouchet & Rocroi (2005): * Turritellinae Lovén, 1847 - synonyms: Zariinae Gray, 1850; Zeacolpini Marwick, 1971; Archimediellidae Starobogatov, 1982; Tachyrhynchinae Golikov, 1986 *Orectospirinae Habe, 1955 *Pareorinae Finlay & Marwick, 1937 *Protom ...

Jane Longstaff
Mary Jane Longstaff, (née Donald; 27 August 1855 – 19 January 1935) was a British malacologist, specialising in fossil gastropods of the Palaeozoic. Early life Mary Jane Donald was born in 1855 in Carlisle. She was the eldest child of Matthew Hodgson Donald, a prominent local industrialist, and his wife Henrietta Maria Roper. She had three younger siblings. She was sent to a private girls' school in London, and then attended the Carlisle School of Art. Although she never had any formal scientific education, she was interested in nature from a very early age, and particularly in snails and other land and freshwater molluscs. Scientific work Donald educated herself. Her first paper on molluscs was read before a local scientific organisation in Cumberland in 1881. J. G. Goodchild, a British Geological Survey expert on northern British geology who was a member of this organisation, suggested that Donald undertake a study of some neglected groups of fossil shells. She subseq ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Species
In biology, a species is the basic unit of Taxonomy (biology), classification and a taxonomic rank of an organism, as well as a unit of biodiversity. A species is often defined as the largest group of organisms in which any two individuals of the appropriate sexes or mating types can reproduction, produce Fertility, fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, morphology (biology), morphology, behaviour or ecological niche. In addition, paleontologists use the concept of the chronospecies since fossil reproduction cannot be examined. The most recent rigorous estimate for the total number of species of eukaryotes is between 8 and 8.7 million. However, only about 14% of these had been described by 2011. All species (except viruses) are given a binomial nomenclature, two-part name, a "binomial". The first part of a binomial is the genus to which the species belongs. The second part is called the specifi ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
