What is growing on that disk?

Today in our Science class we have studied the fouling of our Virtue disks using even stereo microscopes. Andrea and Judit, 1st ESO students have come to help us to identify organisms and we could draw the results on ipads.
Andrea has had the virtue rack placed for five months in Roses.
We saw living “mantis shrimps”, algaes and many other organisms.
It was really interesting!
Have a look at the pics!

Look this is a grown up mantis shrimp, ours are very tiny!
