Gundlachia (gastropod)
''Gundlachia'' is a genus of minute freshwater snails or limpets, aquatic pulmonate gastropod mollusks in the family Planorbidae, the ram's horn snails and their allies. The generic name is in honor of Cuban naturalist Juan Gundlach (1810-1896). Anatomy These animals have a pallial lung, as do all pulmonate snails, but they also have a false gill or "pseudobranch". This serves as a gill as, in their non-tidal habitat, these limpets never reach the surface for air. Distribution They have a worldwide distribution. Species Species within the genus ''Gundlachia'' include:Silvana C Thiengo, Aline C Mattos, M Fernanda Boaventura, Márcio S Loureiro, Sonia B Santos, Monica A Fernandez.

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. Most living animal species are in Bilateria, a clade whose members have a Symmetry in biology#Bilate ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Gastropod
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. The anatomy, behavior, feeding, and re ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Ferrissia Neozelanicus
''Ferrissia neozelanica'', also known as ''Gundlachia neozelanica'', is a species of minute freshwater limpet, an aquatic pulmonate gastropod mollusk, or micromollusk, in the family Planorbidae. As of 2014, this species was listed in the IUCN Red list twice: as ''Gundlachia neozelanica'' - data deficient and as ''Ferrissia neozelanicus'' - least concern. Shell description Shell depressed conoidal, oval-oblong, the sides straightened, subparallel, thin, semitransparent, horn-colour, with a blackish-green coating. Apex a little inclined to the right, situated at the posterior sixth of the length, flatly convex anteriorly; concentric lines of growth at regular intervals. Interior light brown, shining. Aperture is elongated oval, slightly broadened anteriorly. Specimens have been found with the septum partly formed, but not adult.
