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.

Species
In biology, a species is the basic unit of 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 produce fertile offspring, typically by sexual reproduction. Other ways of defining species include their karyotype, DNA sequence, 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 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 specific name or the specific epithet (in botanical nomenclature, also sometimes i ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Assiminea Brevicula Map
''Assiminea'' is a genus of minute, salt-tolerant snails with an operculum, aquatic gastropod mollusks, or micromollusks, in the family Assimineidae.Bouchet, P.; Gofas, S. (2015). Assiminea Fleming, 1828. Accessed through: World Register of Marine Species at http://www.marinespecies.org/aphia.php?p=taxdetails&id=137681 on 2015-04-29 Distribution and habitat These snails can be found worldwide. They live usually in brackish water and salt marshes of tropical and temperate regions, at beaches, in water and at land. Description These are very small to medium large snails, between 2 and 13 mm). Some adults do not exceed a size of 3 mm. The shape of the thin shells is somewhat ovately conical. The margin of the aperture is simple. The operculum is in most cases horny. The eyes are at the end of short, stout stalks. They feed on vegetable detritus and small algae. They lay their eggs in the mud, and hatch as free-swimming larvae. Species According to the World Register o ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
