What is it?

Marovo Lagoon is the largest saltwater lagoon in the world, sitting inside the Solomon Islands in the Pacific Ocean. It is a huge sheltered stretch of sea, surrounded by two long chains of islands covered in thick tropical rainforest. The United Nations has it on a special list of places so beautiful and important that the whole world wants to help protect them.

Tell me more

A lagoon is a calm, sheltered patch of sea that is enclosed or partly enclosed by land or a reef. Marovo Lagoon is extraordinary because it has not just one ring of islands protecting it, but two β€” an outer barrier and an inner barrier β€” making the water inside incredibly calm and clear. You can sometimes see 40 metres down to the coral below.

Inside the lagoon, hundreds of coral reefs shelter fish of every colour: parrotfish that crunch coral with their beaks, clownfish hiding in sea anemones, and enormous Napoleon wrasse fish with humps on their foreheads. Sea turtles glide between the coral gardens, and dolphins often leap alongside the traditional canoes.

The people who live around the lagoon have fished these waters for thousands of years. They know exactly where the fish gather and which corals are healthy. Local communities are now working together with scientists to protect the reef, making sure it stays as bright and alive for the next generation as it is today.

Marovo is also famous for beautiful wood carvings. Local artists carve detailed scenes of ocean life β€” fish, sharks, and crocodiles β€” into dark ebony and rosewood. These carvings are known all over the world and are a way for people here to share their connection to the sea.

Discussion prompts

  1. 01What does it mean for a place to be 'sheltered'? Can you think of other places β€” on land or sea β€” that are sheltered?
  2. 02Why might it be important for local communities to help protect their own lagoon rather than leaving it entirely to outside scientists?
  3. 03Marovo carvings tell stories about the ocean. How do you tell stories about the place where you live β€” through art, food, stories, or something else?

Classroom activity

Draw a bird's-eye view map of Marovo Lagoon. Include: two rings of islands, coral reefs, calm water in the middle, and three animals that live there. Label each animal and add a colour key for the different types of water.
