Species definition

A kind, variety, or type.

A distinct kind; sort; variety; class.

The definition of a species is a group of animals, plants or other living things that all share common characteristics and that are all classified as alike in some manner.

(biology) A group of closely related organisms that are very similar to each other and are usually capable of interbreeding and producing fertile offspring. The species is the fundamental category of taxonomic classification, ranking below a genus or subgenus. Species names are represented in binomial nomenclature by an uncapitalized Latin adjective or noun following a capitalized genus name, as in Ananas comosus, the pineapple, and Equus caballus, the horse.

The consecrated bread or wine of the Eucharist.

Either of the consecrated elements of the Eucharist.

Visible or perceptible presentation; appearance; something perceived.

The totality of natural physical characteristics (appearance, taste, etc.) of bread or wine, these characteristics remaining the same in the consecrated bread or wine of the Eucharist.

(civil law) The form or shape given to materials; fashion or shape; form; figure.

A specific kind of atomic nucleus.

The outward appearance or form of the Eucharistic elements that is retained after their consecration.

A public spectacle or exhibition.

(logic) A class of individuals or objects grouped by virtue of their common attributes and assigned a common name; a division subordinate to a genus.

(chemistry) A set of atoms, molecules, ions, or other chemical entities that possess the same distinct characteristics with respect to a chemical process or measurement.

A group of organisms having many characteristics in common and ranking below a genus. Organisms that reproduce sexually and belong to the same species interbreed and produce fertile offspring. Species names are usually written lower case and in italics, as rex in Tyrannosaurus rex.

(biol.) A naturally existing population of similar organisms that usually interbreed only among themselves, and are given a unique, latinized binomial name to distinguish them from all other creatures.
