"Skeletal banding" is to coral what rings are to trees - and Australian scientists have discovered them in a species of coral that is critical to reef-building.

The banding can show everything from how fast coral is growing and how old it really is (and how long it will live for) to what the environment was like in the past, and how the coral reacted to it.
