Tiny worms are squashed by air bubbles – saved!

No animals were harmed in the making of this film! The freshwater worm Aeolosoma is about 2mm long and very flexible. I got several of them from a sample of algae from a local lake. And I played around with them a bit under the microscope. They reproduce mostly asexually, this means that one worm is able to separate itself to form several. No harm was done to the worms! Worms were returned to the jar after I looked at them under the microscope.
