Valonia ventricosa, commonly known as bubble algae, is a type of green algae found in warm, shallow waters of the world's oceans. It is characterized by its large, spherical, and translucent cells that can grow up to several centimeters in diameter. These algae often form clusters, creating a distinctive appearance in marine environments. This species plays a role in the ecosystem by providing habitat and food for various marine organisms. However, excessive growth can lead to problems, such as blocking sunlight and disrupting the balance of the ecosystem. Valonia ventricosa is often studied for its ecological impact and potential uses in biotechnology.
