Which of the following is considered freshwater marine life?

Bass is considered freshwater marine life because it primarily inhabits lakes, rivers, and other freshwater environments. Unlike tropical reef fish, coral polyps, and sharks, which are adapted to saltwater ecosystems, bass thrives in freshwater habitats, making it a suitable example in this context. Coastal or marine environments contain a different ecological composition, and species associated with those areas, like tropical reef fish or sharks, cannot survive in freshwater. Thus, bass stands out as the correct choice for freshwater marine life due to its characteristic habitat.
