Common name: Red Algae

Halymeniales is an order of red algae primarily found in marine environments. Members of this order are known for their robust, often leathery thalli, which can vary in color from deep red to purple. They are important components of reef ecosystems, providing habitat and food for a variety of marine organisms. Some species within this order are also explored for their potential in biotechnology due to their unique chemical compounds. For reefkeeping, they can add diversity and color to an aquarium, but their growth should be monitored to prevent overtake of other sessile organisms.
