This term can be used in various fields, such as biology or ecology, to describe organisms that thrive in diverse conditions or that engage with a range of different species.

Heterophilic: Referring to the attraction or affinity for different species or types; in biological contexts, it often describes organisms or cells that interact or react with different types of cells or organisms. This term can be used in various fields, including immunology, where it may refer to antibodies that recognize antigens from different species, or in ecology, describing interactions between different species.
