Footage shows coral stirring water
Coral reefs may look static to the naked eye, but scientists have now seen "violent" activity on their surface.
Using powerful microscopes, researchers filmed this footage showing microscopic hairs on the surface of corals "stirring up" the surrounding water.
They say that these swirls of water draw nutrients towards the coral, and may also drive away potentially toxic waste products.
