A group of individuals agreeing in common attributes, and designated by a common name; a conception subordinated to another conception, called a genus, or generic conception, from which it differs in containing or comprehending more attributes, and extending to fewer individuals. Thus, man is a species, under animal as a genus; and man, in its turn, may be regarded as a genus with respect to European, American, or the like, as species.
In science, a more or less permanent group of existing things or beings, associated according to attributes, or properties determined by scientific observation.

a group of animals or plants of the same kind ....... back
A group of organisms (individuals) that can interbreed and reproduce with each other. Used to distinguish sexually reproducing organisms into groups. Individuals from two different species cannot have offspring. They are said to be reproductively isolated. The biologist Ernst Mayr formulated this definition of a species advancing our understanding of the mechanism of evolution of higher organisms. For microbes, the species definition does not properly apply, because they do not reproduce sexually, but have an efficient mechanism to exchange genetic material even between evolutionarily distant forms. This exchange of genes is known as horizontal gene transfer. Unlike sexual reproduction, it usually involves only a fraction of an organisms genome that is being transferred and is a mechanisms of increasing genetic variability among microorganisms that does not depend on cellular reproduction (cell division).

It is hard to define a species absolutely because the process of one species becoming two or changing into another species is so slow that there is no point at which one can say 'Now! It's a different species from yesterday!'. The most simple definition is a group of organisms that can breed together to produce fertile offspring. Species are the smallest unit of biological taxonomy, and are grouped together with similar species to form a genus.

Usually, different species cannot interbreed but this rule is not absolute (for example, a horse and donkey can interbreed to produce a mule, although this animal cannot reproduce, see hybrid). Even within one species, interbreeding may not always occur because of natural barriers. Among some plants and many micro-organisms, the concept of a species does not always work. In these groups, species that appear different may be able to successfully create offspring under certain circumstances.
a group of similar organisms that have a shared origin and the ability to breed freely with one another.
The basic category in the Linnaean sequence. A species may best be defined as a group of inter-breeding individuals with so many features in common that they form a distinct, and generally recognisable, group. In practice, the interbreeding criterion cannot always be used, for example with fossils, so species can often only be defined subjectively. One or more species are included in a genus. more on the species concept
a group of individuals taxonomically ordered according to common attributes and designated by a common name.
A single type of plant or animal, not a group like genus or family. Each species has a two-word scientific name that includes the name of the genus it belongs to and then the name of the species. Another way to think of this is the Genus is the "Generic" name and the Species is the "Specific" name.

All plants and animals are divided into groups with similar characteristics. The basic building block for this division is the species. Organisms of the same species can interbreed. Species with common characteristics are grouped into a genus (plural genera). Genera with similar characteristics are grouped into a family. Each species is given a scientific name of two words, the genus and species. These names are latin so they can be recognized worldwide. Common names, on the other hand, vary from nation to nation, and even within a nation. Examples: Species: Mallard Scientific Name: Anus platyrhynchos Species: Northern Pintail Scientific Name: Anus acuta Both the Mallard and Pintail are in the same genus Anus and are also grouped into the family of ducks, geese, and swans.

A group of individuals, usually identifiable by a set of distinctive features, with a unique evolutionary history. Classically, the members of a species can interbreed only with each other to produce fertile offspring.
a class or specific type of organism; a group of individuals related by descent, and able to breed among themselves but not with other animals
(sp' sh z) The category of organization for taxonomy below genus, representing animals capable of interbreeding with each other. The scientific name for a species is generally written with the genus in binomial form. Example: Homo sapiens.
the basic unit of Linnaean classification; a taxonomic subdivision of genus represented by plants that can freely interbreed but rarely with other species. In the scientific name Sambucus nigra, the genus is Sambucus and the species epithet is nigra ; together Sambucus nigra constitutes the species
A group of animals or plants having common characteristics and able to breed together to produce fertile (capable of reproducing) offspring, so that they maintain their â€˜separateness' from other groups. For example, yellowfin tuna and bigeye tuna are two distinct tuna species, whereas general terms like â€˜tuna' and â€˜trout' each represent groups of species.
a taxon comprising one or more populations of individuals capable of interbreeding to produce fertile offspring.
seeing, appearance, shape, kind or quality
the smallest classification group of organisms. organisms of the same species mate and produce healthy young
subdivision of biological classification composed of related organisms that share common characteristics and can interbreed.
Group within a genus, the members of which share similar characteristics and can breed successfully together.
The basic unit of biological classification. This definition is open to very wide interpretation and what one person regards as just another species, may be seen by someone else, to be a totally separate genus or only a form.
A group of plants or animals that have certain common features which set them apart from others.
The species, an adjective, often refers to a place, the plant's characteristics/appearance, or the name of the person credited with discovering it. Species is abbreviated sp. or spp.
Different definitions are available dependent upon the characters being used to define a species. See also biological species concept, morphospecies concept and phylogenetic species concept.... More

(1) a group of organisms that have a unique set of characteristics (like body shape and behavior) that distinguishes them from other organisms. If they reproduce, individuals within the same species can produce fertile offspring. (2) the basic unit of biological classification. Scientists refer to species using both their genus and species name. The house cat, for example, is called Felis catus.
the taxonomic division of freely interbreeding population of wild or naturally occurring individuals below genus.
Living things of the same kind that are potentially capable of breeding and producing fertile offspring. Theoretically, plants or animals of different species cannot interbreed. However, occasionally this does not hold true.

pl. A category of classification, ranking below a genus, consisting of closely related organisms capable of interbreeding. An organism belonging to a species is represented by an uncapitalized Latin name and a capitalized genus name, as in Hyacinthoides non-scripta, the Bluebell.
all the populations of organisms that are capable of breeding under natural conditions and that are reproductively isolated from other organisms; the basic lower unit of biological classification.
the basic unit of taxonomy. A species is defined as a group of individuals that are genetically related and can interbreed to produce fertile young of the same kind.
the basic category of biological classif ication, designating a single kind of animal or plant. Abbreviation: sp. &endash; plural: spp.
The most basic level by which plants and animals may be grouped. Scientists have an ongoing friendly debate about how to define a species. One commonly held view is that the group is the lowest level of organisms that can breed with one another and that cannot breed freely with other groups of plants and animals. As technology allows researchers to peer ever more deeply into the genetic makeup of organisms, the definition comes under increasing challenge. Perhaps the most valuable characteristic of a species is the fact that it’s the basic unit of classification.
a group of very similar plants. Species are grouped together into Genera.
A gem with distinct characteristics that are well defined.
a group of organisms that breed with each other to produce fertile offspring.
A distinct group of organisms that interbreed to produce organisms substatively the same as the parents. Species roses are roses that appear naturally in the wild - at least most of them are.
As usually used within this article, a species is a reproductively isolated group of organisms capable of interbreeding in the wild and producing viable, fertile offspring. This is known as the Biological Species Concept (BSC). An alternative statement of the BSC defines a species as the most inclusive group of sexual and cross-fertilizing individuals which share a common gene pool. However, this concept breaks down for asexual species, fossil species, and even sexual species in many cases. In reality there are only degrees of reproductive and genetic isolation, so species are not absolute entities. Joseph Boxhorn has given a more detailed analysis of the species concept in the "Observed Instances of Speciation" FAQ. Note, the BSC has interesting implications for the nature of the last universal common ancestor of all life, especially if horizontal genetic transfer was extensive then (as it is today between the different unicellular "species" of bacteria, archaea, and eukaryotes).

Different types of plants e.g. cocksfoot and ryegrass are different species
Species generally grouped for marketing convenience and identified with a single commercial name. (See ASTM D 1165, Standard Nomenclature of Domestic Hardwoods and Softwoods, for commercial practice in the United States and Canada.)
a group of organisms that are similar in structure and can mate and produce fertile offspring
species is a group of living things that breed with each other in nature and produce offspring that can also breed. Coyotes can breed together, and the pups can breed when they grow up, so all coyotes are one species. Bobcats can't breed with coyotes, so they're a different species. In nature, living things in the same species usually look pretty much alike.
A taxon of the rank of species; in the hierarchy of biological classification the category below genus; the basic unit of biological classification; the lowest principal category of zoological classification.
Organism classification that includes individuals that share the same heredity, are similar in morphology and behaviour, and can produce similar offspring.
A subdivion of a genus in the classification of plants. Species of plants are distinguished by the characteristics of fruits,flowers, leaves, bark and wood.
The basic unit of classification in biology. Examples are the bald eagle, the polar bear, the monarch butterfly, and the tawny mole cricket. The word is both singular (a species) and plural (two species). Species are grouped into genera, and genera are grouped into family. The words kind, sort, type, strain, and variety are not part of this classification even though newspaper reporters often use them as if they were.
A group of related organisms with common characteristics that are capable of interbreeding. Loblolly and Virginia pine are examples of two different tree species.
A group of biological organisms that interbreed to produce fertile offspring or possess common characteristics derived from a common gene pool.

taxonomic group whose members can interbreed
Group of animals or plants with common characteristics
A taxonomic category subordinate to a genus (or subgenus) and superior to a subspecies or variety, composed of individuals possessing common characters distinguishing them from other categories of individuals of the same taxonomic level. In taxonomic nomenclature, species are designated by the genus name followed by a Latin or Latinised adjective or noun.
In the same or like form or kind. For the purposes of the CWCP, we refer to scientific animal groupings of genus and then a subgroup called "species."
A group of living things that can interact to produce offspring like themselves. Tigers do not have lion cubs, and an eagle and owl cannot interact to produce offspring like themselves.

The basic unit of living things, consisting of a group of individuals which all look more or less alike and which can all breed with each other to produce another generation of similar creatures. Many species are subdivided into sub-species. These normally inhabit different areas and they may differ in appearance, but they can still all interbreed.
a group of living things that share common biological characteristics
Plant species are usually variable in the wild and may be split into three botanically recognized but occasionally overlapping subdivisions; the subspecies (subsp.), the variety (var.) and the form (forma, f.).

An established classification into which similar individuals in the plant or animal kingdom are placed. A species is described as a morphologically distinctive and genetically isolated natural population.
A particular type of plant, animal, or other organism. Species differ from one another in at least one characteristic, and generally do not interbreed. In biology, species is a category that's part of the scientific system for grouping together related plants, animals and other organisms (kingdom, phylum, class, order, family, genus, species).
Used to refer to individual gems that have distinct characteristics which may be defined and verified.
A group of animals or plants that share similiar characteristics such as can reproduce.

Basic classification unit of plants comprised of individuals that are recognized as distinct from other species, and which can freely interbreed among themselves.
A set of individuals sharing distinctive characteristics likely to produce common, fertile descendents. The notion of species is used in its broadest sense here and refers not only to species proper but also to subspecies, isolated geographic populations, strains and varieties, whether plant or animal.
a genetically distinctive group of natural populations that share a common gene pool that are reproductively isolated from all other such groups.
a group of closely related individuals that have the potential to reproduce with each other; a unit of classification.
A "species" is generally accepted as a group of individuals that look the same and can breed with each other but not usually with individuals of another species. "Species" is the the lowest level of plant classification. This is part of the science called " taxonomy". Scientists refer to living things by a combined "genus" and "species" name, using Latin terms. For example, people are called " Homo sapiens". A white pine would be called " Pinus strobus". A scientist anywhere in the world can look up information about any living organism by knowing the Latin or scientific name. The genus name is always capitalized. The species name is usually not capitalized. Incidentally, the word " specie" is incorrect. " Species" is the correct singular and plural form of the word.

In biology a species generally taken to be either the lowest level of taxonomic classification or a group of interbreeding individuals that are reproductively isolated from other organisms. A species in biology is not a "kind" in Plato's sense of the word.
This is the scientific, taxonomic name of a living thing.
In plant classification, a group of plants with common characteristics that can cross-breed with one another.
a group of organisms that mate freely in nature and can produce viable offspring
Populations whose individuals freely breed with one another and vary only slightly from one another.
The basic category of biological classification consisting of similar organisms that are capable of mating and reproduction
is one of the most specific of several levels of classification for a plant. They are ranked in levels from largest to smallest groupings first by kingdom, then by phylum, class, order, family, genus, and species.
The name of a category that is part of the scientific classification of all organisms. The category species is located in the classification system after kingdom, phylum, class, order, family and genus. Humans, for example, belong to the species sapiens and are identified by the scientific name Homo (genus) sapiens (species).
A group of closely related organisms that are capable of interbreeding and are reproductively isolated from other groups of organisms (in other words, they can breed among themselves and not with others); the basic unit of biological classification.
Major subdivision of a genus of plants. A biological classification composed of related plant individuals.
The type of wood, such as spruce or fir. Each species has different characteristics as well as strengths and weaknesses.
A group of organisms that can interbreed under natural conditions to produce fertile offspring

(n) A group of animals or plants within a genus differing only in minor details form the others, and able to breed with each other but not with other groups
An internationally established botanical classification of trees.
a genetically distinct group, consisting of related individuals that resemble each other in appearance and behavior, and can breed among themselves but not, with some exceptions, with other species
1. In biological classifications, it is the lowest and most basic unit of the Linnaean taxonomic hierarchy (although it is also divisible into subspecies), and one of the two required titles of a binomial name. In nature, a species is a group of organisms that breed only amongst themselves and produce offspring that are also capable of reproducing. 2. In chemistry, a group of constituents or molecules, that share major chemical similarities. For example, Hg0 and Hg+2, or CO and CO2.
Abbreviated to spp. (singular = sp.). A group of individuals which interbreed with each other, but generally not with other species.
A fundamental category of taxonomic classification, ranking below a genus.
A group of related organisms which are capable of interbreeding.
In classification, a species is a group of closely related organisms that can reproduce. A group of similar species forms a genus. In the scientific name of an organism, the second name is its species (for example, people are Homo sapiens - our species is sapiens).
The biological species concept is the most widely accepted method for categorizing living species, especially for vertebrates. It defines a species as members of populations that actually or potentially interbreed in nature, not according to similarity of appearance. Although appearance is helpful in identifying species, it does not define a biological species.
A single, distinct class of living creature with features that distinguish it from others.
a group of plants or animals that are of the same type or origin
A group of interbreeding individuals, not interbreeding with another such group, being a taxonomic unit including two names in binomial nomenclature, the generic name and specific epithet, similar and related species being grouped into a genus. From the Latin, species, "particular kind."
Related strains of a plant that occur naturally.
A group of organisms that are biologically capable of exchanging genes with each other but are incapable of exchanging genes with other such groups.
n: The boundaries of this taxonomic level (the most precise in the hierarchical system of binomial nomenclature ) are hotly debated among scientists and there is little real consensus about where to draw the lines between species, subspecies, morphs, races, variants, etc. In general, a species is a group of organisms that resemble one another in appearance, general behavior, ecological niche, chemical makeup and processes, and genetic structure. Organisms that reproduce sexually are classified as members of the same species only if they can actually or potentially interbreed with one another and produce fertile offspring. It should be noted that some (though quite few) taxonomists believe the species level of classification is frequently invalid and these scientists only recognize classifications down to the level of genus (again, these taxonomists represent a very small minority view).
Fundamental unit of biological taxonomy. Generally spoken, two individuals belong to the same species if they can produce fertile offspring
The basic category of biological classification, displaying a high degree of mutual similarity determined by a consensus of informed opinion; a subcategory of genus. ( 16)
Group of closely related individuals, resembling one another in certain inherited characteristics.
In biology, a species is one of the basic units of biodiversity. Species is the smallest group of classification. A species generally consists of all the individual organisms of a natural population which are able to interbreed, generally sharing similar appearance, characteristics and genetics due to having relatively recent common ancestors.
Species (used as a noun) in metaphysics are defined by their genus (genos) and differentia (diaphora).
The Species film series is the group of films that take place in the Species universe.
