We have 20 images that shows the breathtaking wildlife and reefs that call them home and remind us why we should be working so hard to protect them.

12. 13 World Oceans Day
Lionfish on the coral reef at Turks and Caicos. The lionfish are considered an invasive species after they quickly spread their geographic ranges in the early 21st century. This disrupted the balance of ecosystems and threatened the well-being of coral reefs and other marine ecosystems. Science agencies are working hard to stop further spread and control the existing population. | other Photo: third party
