Quizplus · Accepted Answer

Aquatic organisms with a lower ionic concentration in their body fluids than their surroundings are known as hypoosmotic organisms. This means they have a higher water concentration in their bodies and tend to lose salt and other ions to their surroundings. Examples of hypoosmotic organisms include freshwater fish, some amphibians, and some invertebrates.
