Spirostomum sp. ciliate protozoan,coloured scanning electron micrograph (SEM). These tiny single-celled organisms are found in freshwater and marine habitats. It feeds on bacteria and decaying organic matter,which it filters through membranelles in its primitive mouth,known as a buccal cavity. The membranelles,rows of fused cilia (short microscopic hairs),are also used for locomotion. Magnification: x300 when printed at 10 centimetres wide | |
