Christophe Brochard gave advice how to film. Anne Schumacher caught the plankton and Anne and Sanne Moedt made a first set-up to film in a dark bedroom. Than Yuta Morii took the aquarium to his room and spent part of the night making clips. Maarten edited three clips into one movie. The cumb jelly shows the prisms of the combs. Than there is the seaangel. A flying snail and predator of sea butterflies. Unfortunately we have not been able to catch sea butterflies yet. When the sea angel finds a sea butterfly, it opens a circle of tentacles on the top of its head and within a second, the sea butterfly is swallowed. The black dot in the stomach of the sea angel is its previous meal. After that you can see a large copepod too.
