Green limu thrives where sunlight reaches the seafloor-from rocky tide pools to shallow reefs and nearshore waters.
More than just seaweed, green limu plays an important role in Hawaiʻi’s marine ecosystems and connects land, ocean and people.
Green limu occurs naturally in Hawaiʻi and other places in the world through processes like dispersal in currents.
A sign of a healthy, balanced ocean, green limu helps indicate good water quality and overall ocean health.
Provides food for a variety of marine life, including fishes andHawaiian green sea turtles (honu). and offers shelter in coastal habitats.
A favorite food for honu (Hawaiian green sea turtles) and many fishes, green limu helps support marine biodiversity and healthy coastal ecosystems.
Oxygen Producers
About 50% of Earth’s oxygen comes from marine algae and phytoplankton. Limu supports marine life and Hawaiian coral reef ecosystems by saturating tide pools and coral reefs with oxygen.
