Chaetomorpha is a genus of green algae commonly found in marine environments. It typically appears as long, filamentous strands that can form dense mats in shallow waters. This algae thrives in nutrient-rich conditions and is often associated with coastal ecosystems. These algae play a crucial role in their habitats by providing food and shelter for various marine organisms. Chaetomorpha can also help improve water quality by absorbing excess nutrients, making it an important component of coastal ecology and a potential tool for managing eutrophication.
