Synura collapsing at the air-water interface
Species name:Synura
AL-Museum AL-Museum
A colony of brown flagellates, Synura, rolls slowly along the surface of particles or quickly rotates in open water. When it reaches the outer boundary of water and encounters air, it must stop. Here, some contents of the colony are gradually discharged. The flagella of each flagellate stop waving as the whole colony shrinks and finally collapses with the flagellates floating apart.
