While changing the soil of an old pot, students have discovered a hammer-head platelminto. One of the most amazing animal on Earth... and on space as the species of its family are used a lot by space researchers (more info here).
Our school bug-expert (thank you Craig!) have cross-checked if this specie was not invasive as they are known to eat earthworm. It would have been a risk for our garden and our island.
But no worries, our new friend is part of PSWS!
