Species \Spe"cies\, n. sing. & pl. [L., a sight, outward appearance, shape, form, a particular sort, kind, or quality, a species. See Spice, n., and cf. Specie, Special.]

  1. Visible or sensible presentation; appearance; a sensible percept received by the imagination; an image. [R.] ``The species of the letters illuminated with indigo and violet.''
    --Sir I. Newton.

    Wit, . . . the faculty of imagination in the writer, which searches over all the memory for the species or ideas of those things which it designs to represent.

    Note: In the scholastic philosophy, the species was sensible and intelligible. The sensible species was that in any material, object which was in fact discerned by the mind through the organ of perception, or that in any object which rendered it possible that it should be perceived. The sensible species, as apprehended by the understanding in any of the relations of thought, was called an intelligible species. ``An apparent diversity between the species visible and audible is, that the visible doth not mingle in the medium, but the audible doth.''

  2. (Logic) 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.

  3. In science, a more or less permanent group of existing things or beings, associated according to attributes, or properties determined by scientific observation.

    Note: In mineralogy and chemistry, objects which possess the same definite chemical structure, and are fundamentally the same in crystallization and physical characters, are classed as belonging to a species. In zo["o]logy and botany, a species is an ideal group of individuals which are believed to have descended from common ancestors, which agree in essential characteristics, and are capable of indefinitely continued fertile reproduction through the sexes. A species, as thus defined, differs from a variety or subspecies only in the greater stability of its characters and in the absence of individuals intermediate between the related groups.

  4. A sort; a kind; a variety; as, a species of low cunning; a species of generosity; a species of cloth.

  5. Coin, or coined silver, gold, or other metal, used as a circulating medium; specie. [Obs.]

    There was, in the splendor of the Roman empire, a less quantity of current species in Europe than there is now.

  6. A public spectacle or exhibition. [Obs.]

  7. (Pharmacy)

    1. A component part of a compound medicine; a simple.

    2. (Med.) An officinal mixture or compound powder of any kind; esp., one used for making an aromatic tea or tisane; a tea mixture.

  8. (Civil Law) The form or shape given to materials; fashion or shape; form; figure.

    Incipient species (Zo["o]l.), a subspecies, or variety, which is in process of becoming permanent, and thus changing to a true species, usually by isolation in localities from which other varieties are excluded.

Douglas Harper's Etymology Dictionary

late 14c. as a classification in logic, from Latin species "a particular sort, kind, or type" (opposed to genus), originally "a sight, look, view, appearance," hence also "a spectacle; mental appearance, idea, notion; a look; a pretext; a resemblance; a show or display," typically in passive senses; in Late Latin, "a special case;" related to specere "to look at, to see, behold," from PIE *spek- (see scope (n.1)). From 1550s as "appearance, outward form;" 1560s as "distinct class (of something) based on common characteristics." Biological sense is from c.1600. Endangered species first attested 1964.


n. 1 A type or kind of thing. 2 # A group of plants or animals having similar appearance.

  1. n. (biology) taxonomic group whose members can interbreed

  2. a specific kind of something; "a species of molecule"; "a species of villainy"

Species (disambiguation)

Species is one of the basic units of biological classification.

Species may also refer to:

Species (metaphysics)

Species, in metaphysics, is a specific genus-differentia defined item that is described first by its genus (genos) and then its differentia (diaphora). Put differently, it is an item, not necessarily biological, that belongs to a group and can be distinguished from other species in that group.

For example, a human being as a species can be defined as an animal (genus) that can reason (differentia).

The term is derived from the Greek word eidos, which means form in Plato's dialogues but should be taken to mean species in Aristotle's corpus.

Species (Christianity)

Species is an older English word meaning 'external form or appearance'. In Christianity, when the wine is turned into blood, it is believed to literally become blood, which then retains only the species of the wine, meaning the appearance, taste, smell and feel of the wine.

Category:Christian terminology

Species (film)

Species is a 1995 American science fiction horror thriller film directed by Roger Donaldson and written by Dennis Feldman. It stars Natasha Henstridge, Ben Kingsley, Michael Madsen, Alfred Molina, Forest Whitaker and Marg Helgenberger. In the film, a motley crew of scientists and government agents tries to track down an alien seductress played by Natasha Henstridge before she successfully mates with a human male. Due to her ruthlessness, the alien character was cited as an example of negative treatment of female sexuality and aliens by the Hollywood film industry. The design of Sil was also linked to a chupacabra sighting.

The film was conceived by Feldman in 1987, and was originally pitched as a film treatment in the style of a police procedural, entitled The Message. When The Message failed to attract the studios, Feldman re-wrote it as a spec script, which ultimately led to the making of the film. The extraterrestrial in Species, an alien woman named Sil, was designed by H. R. Giger, also responsible for the beings from the Alien franchise. The effects combined practical models done by Giger collaborator Steve Johnson and XFX, with computer-generated imagery done by Richard Edlund's Boss Film Studios. Giger felt the film and the character were too similar to Alien, so he pushed for script changes.

Most of the principal photography was done in Los Angeles, California, where the film is set. Several scenes were filmed in Utah and at the Arecibo Observatory in Puerto Rico. The film was poorly received by critics, but nevertheless turned out to be a box office success, grossing US$113 million ($ million in dollars). It spawned one theatrical sequel ( Species II), as well as two direct-to-video sequels ( Species III and Species: The Awakening). Species was adapted into a novel by Yvonne Navarro and two comic book series by Dark Horse Comics, one of which was written by Feldman.


In biology, a species (abbreviated sp., with the plural form species abbreviated spp.) is one of the basic units of biological classification and a taxonomic rank. A species is often defined as the largest group of organisms in which two individuals are capable of reproducing fertile offspring, typically using sexual reproduction. While in many cases this definition is adequate, the difficulty of defining species is known as the species problem. For example, a species complex is a group of closely related species that are very similar in appearance to the point that the boundaries between them are often unclear. Differentiating measures include similarity of DNA, morphology, or ecological niche. Presence of specific locally adapted traits may further subdivide species into " infraspecific taxa" such as subspecies (and in botany other taxa are used, such as varieties, subvarieties, and formae).

Species hypothesized to have the same ancestors are placed in one genus, based on similarities. The similarity of species is judged based on comparison of physical attributes, and where available, their DNA sequences. All species are given a two-part name, a "binomial name", or just "binomial". The first part of a binomial is the generic name, the genus to which the species belongs. The second part is either called the specific name (a term used only in zoology) or the specific epithet (the term used in botany, which can also be used in zoology). For example, Boa constrictor is one of four species of the Boa genus. While the genus gets capitalized, the specific epithet does not. The binomial is written in italics when printed and underlined when handwritten.

A usable definition of the word "species" and reliable methods of identifying particular species are essential for stating and testing biological theories and for measuring biodiversity, though other taxonomic levels such as families may be considered in broad-scale studies. Extinct species known only from fossils are generally difficult to assign precise taxonomic rankings, which is why higher taxonomic levels such as families are often used for fossil-based studies.

The total number of non- bacterial and non- archaeal species in the world has been estimated at 8.7 million, with previous estimates ranging from two million to 100 million.

Usage examples of "species".

I think this must be admitted, when we find that there are hardly any domestic races, either amongst animals or plants, which have not been ranked by some competent judges as mere varieties, and by other competent judges as the descendants of aboriginally distinct species.

But to extend the hypothesis so far as to suppose that species, aboriginally as distinct as carriers, tumblers, pouters, and fantails now are, should yield offspring perfectly fertile, inter se, seems to me rash in the extreme.

I have ever conversed, or whose treatises I have read, are firmly convinced that the several breeds to which each has attended, are descended from so many aboriginally distinct species.

In some cases, I do not doubt that the intercrossing of species, aboriginally distinct, has played an important part in the origin of our domestic productions.

For when it is stated, for instance, that the German Spitz dog unites more easily than other dogs with foxes, or that certain South American indigenous domestic dogs do not readily cross with European dogs, the explanation which will occur to everyone, and probably the true one, is that these dogs have descended from several aboriginally distinct species.

Evidently, the Acme shop simply carried red primroses, of the species primula obconica because there was a call for them.

His upper lip was furry and mobile, making his face more expressive than those of earlier adapid species.

Throughout our history we have proved to be a remarkably adaptable species.

Hence since it is seen in its proper species, and is adored in heaven, it is not seen under its proper species in this sacrament.

She had found four species that adsorbed heavy metals, and two that absorbed dissolved silicates and fixed them into their rigid stalks.

Pleistocene Age, when the world warmed up and people became much more mobile, and that the cultivation of wild species, before agriculture proper, encouraged the birth of more children.

Among the molluscs and zoophytes, I found in the meshes of the net several species of alcyonarians, echini, hammers, spurs, dials, cerites, and hyalleae.

Because they evolved rapidly, had worldwide distribution by virtue of their open-water habitats, and species are readily distinguished, ammonoids are index fossils for the Jurassic.

Fourteen species of autotrophic nannoflagellates, twenty heterotrophic flagellates, forty heterotrophic dinoflagellates, and several metazoans, including polychaetes, amphipods, copepods, euphausids, and fish.

Meanwhile, thanks to the genius of our Ancestral Hosts, we have found a way to reclaim some of our lost species.
