👉 Musses are a type of fish that live in freshwater. They can be found in many different places around the world, including rivers, lakes, and even some bodies of water like streams or ponds. Mussel shells are also commonly used as a food source for humans, although they have been linked to certain health issues such as ichthyosis (a condition where skin becomes too thick due to overgrowth of mussels), and may be harmful to certain fish species.
