In this special episode of Deadly 60, Steve Backshall takes a deep dive into the fate of one of the most extraordinary, and endangered, ecosystems on our planet: coral reefs. They may cover less than one per cent of the ocean floor, but they support roughly a quarter of all marine life and are irreplaceable - yet they are in serious trouble.  Steve travels to some of the world's most celebrated reef systems, from the shallows of the Java Sea to the tropical waters of the Maldives. Along the way, he meets all the weird and wonderful creatures that call the reef home, including some of the best-camouflaged creatures and some impressive apex predators - he even gets a telling-off from a clownfish!
