Nano-CT of a bryozoan

Bryozoans are tiny colonial animals that generally, but not always, build skeletons of calcium carbonate. This particular example is similar in structure to a coral.

The Gatan X-ray Ultra Microscope allows the 3D visualisation of the internal pore structure which may hold information on how the organism grows.
