2. Species that have adapted to survive and flourish in habitats with increased osmotic pressure
3. Microbial life forms exhibiting a preference for and resilience in osmotically challenging conditions

Etymology: Osmophiles is the plural of "osmophile", and the word is built from two parts. The first, "osmo-", comes from the Greek "ōsmos", meaning "push" or "impulse", and it gave English the term "osmosis", the movement of a solvent across a membrane. The second, "-phile", comes from the Greek "philos", meaning "loving" or "friend", and appears in many scientific coinages for organisms that favour a particular condition, such as thermophiles that like heat. Put together, an osmophile is an organism that "loves" high concentrations of dissolved substances, which the environment forces on it. Salty brines and sugar-rich foods are the usual examples, and the word describes the organism's preference rather than any harm done to it.
