It’s about the size of a diamond and comes from the inner ear of a fish. This tiny construction holds a treasure trove of information, a calcium carbonate microchip made of bone and accessed by a laser. Let’s take a look at the science of otoliths.

The deep ocean, the last unexplored terrestrial […]
