What does interspecies mean?
Interspecies describes a relationship, interaction, or arrangement involving organisms from more than one species. It is commonly used in discussions of animal behaviour, ecology, communication, breeding, conservation, and cooperation: examples include interspecies communication between animals and interspecies relationships in marine ecosystems. The term can also refer more broadly to interactions that cross species boundaries, such as the relationship between humans and other animals or the effects of human activity on wildlife. It is distinct from “intraspecies,” which concerns members of the same species. In general writing, “interspecies” is clear and direct, although the related adjective “interspecific” is often preferred in formal scientific contexts. The word is useful when the focus is not simply on one species but on the connections, exchanges, or dependencies that exist between different species.
Existing or occurring between different species, or involving organisms of different species.
"The researchers observed an unusual pattern of interspecies cooperation."
Usually used before a noun, especially in expressions such as “interspecies communication” and “interspecies interaction.”
A relationship or interaction between different species.
"The documentary examines the interspecies between the wolves and the wolves' natural prey."
This noun use is less common than the attributive adjective use.
The plural is not commonly used; the word is normally encountered as an attributive adjective or in the uncommon noun sense.
"The study compares several examples of interspecies in tropical forests."
Interspecies communication reminds us that language is not the only way animals can exchange information.
