CT scan


Micro CT scan of 2 valves of Magallana gigas found on Sylt. The sample held 31 worms, of which 18 Polydora websteri (others were a few nereids, P. ciliata and some nematodes). Scan starts ventrally and moves towards the hinges in a coronal plane. The amount of radiation used is about the same as one’d use to visualize a human wrist.

Here some examples of blisters:

And here the burrowing holes, they can be followed all through the oyster shells in the moving CT scan. Only marked a few, otherwise I’d be marking them all day, there are many!

The cute little bivalves that can be seen at the beginning of the scan.
