Saline environments are areas where the concentration of salt is significantly higher than in freshwater. These environments include oceans, seas, and salt flats, where saltwater can reach salinity levels of 35 parts per thousand or more. The high salt concentration affects the types of organisms that can thrive there, leading to unique ecosystems. Organisms in saline environments, such as halophiles and marine life, have adapted to survive in these harsh conditions. They possess specialized mechanisms to manage salt intake and maintain cellular function. These adaptations allow them to flourish in environments that would be inhospitable to most freshwater species.
