organism

A particular organism or defined group of organisms considered to be taxonomically homogeneous.

Instances of the dwc:Organism class are intended to facilitate linking one or more dwc:Identification instances to one or more dwc:Occurrence instances. Therefore, things that are typically assigned scientific names (such as viruses, hybrids, and lichens) and aggregates whose occurrences are typically recorded (such as packs, clones, and colonies) are included in the scope of this class.

A specific bird. A specific wolf pack. A specific instance of a bacterial culture.
