Conspecific
An individual belonging to the same biological species as another. Used in ecology and behavior to describe interactions between members of the same species, such as mice assessing health cues from a conspecific via odor signals.
A conspecific is an individual belonging to the same biological species as another. This term is used in ecology, evolutionary biology, and behavior to distinguish interactions between members of the same species from those between different species. For example, mice assessing health cues from a conspecific rely on odor-mediated signals that convey information about immune activity and social status.
What this means in real life
When two wolves from different packs meet in the wild, they recognize each other as conspecifics and may compete for territory or mates, whereas they would ignore a passing deer as a different species entirely.
What it isn’t
It does not mean 'similar-looking' or 'related.' Two animals can look nearly identical but belong to different species (not conspecific), while conspecifics may look quite different if they're different sexes or ages of the same species.
Commonly misused online
People sometimes use it to mean 'living in the same place' or 'coexisting,' when it strictly refers only to species membership, not habitat or location.
