When it comes to ocean life, you might assume that the real action occurs down in the depths. After all, that’s where sharks, whales, octopi and other stars of sea do their thing, not to mention the truly weird and wonderful creatures that inhabit the ocean floor.
Wouldn’t it be nifty if there was a way we could see into rocks without having to break them? Just think of it.
