Chile has created a new law protecting the waters along its 6,400km (4,000 mile) coastline. The president signed the decree, which creates nine marine reserves.
The new legislation will increase the area of sea under Chilean state protection from 4.3% to 42.4 %, and protect marine life in around 1.4 million square kilometres of sea.
One of the new reserves covers the area around the Diego Ramírez Islands, home to sea lions, kelp forests and whales. Another covers the island around the Juan Fernández Islands.
