What is a common misconception about salmon and lampreys?

The idea that salmon and lampreys cannot coexist is a common misconception because, in reality, both species can share the same aquatic environments without necessarily leading to the decline of either. Salmon and lampreys have different ecological niches and roles within their ecosystems, allowing them to inhabit overlapping areas in rivers and lakes. Salmon are well-known for their role in the food chain, whereas lampreys, being parasitic, have a different interaction with their environment. Understanding that both can thrive together debunks the myth of their incompatibility, highlighting the complexity and interrelatedness of aquatic ecosystems rather than a simplistic view of competition.
