A reef is an aquatic hard-bottom community or habitat, with topographic relief. Reefs can be made of organisms (ie. coral or oysters), rocks, or man made structures.

This is the world's largest coral reef, the Great Barrier Reef. It is over 2300 km in length, and the only living organism visible from space. The Great Barrier Reef lies off Australia's northeast coast, in the Coral Sea.
The depth of the Great Barrier Reef varies. The coral which makes up the Great Barrier reef is believed to extend to a depth of around 500m in some places, but the actual living polyps only go down as far as 30 metres. The water in the channel between the shoreline and the reef reaches about 60 metres in depth.
