@tardibabe: Beautiful creatures can be found in the most unexpected places! 🥹 Here are the microbes I found: Clip 1: colonial green algae named Gonium. They can be found around the globe in freshwaters and are usually composed or 4, 8, 16 or 32 cells. They have the ability to swim toward a light source with the help of their two flagella so they can produce sugars by photosynthesis. Clip 2: a unicellular organism named Colpoda that loves to feed on algae and move with the help of thousands of tiny hairs, called cilia, beating together! Clip 3: a multicellular worm called Aeolosoma which is in the same group than earth worms. They feed on degraded plant material like dead leaves but also on protozoa, bacteria and algae. They ingest food like a small vacuum, by creating a suction with their mouths while their ventral cilia push debris inside it! Clip 4: a unicellular organism, most probably a Litonotus lamella, that loves to feed on bacteria and small microbes! Like Colpoda, this creature is a ciliate that moves with the help of thousands of microscopic hairs beating together. Clip 5: a Hypotrich ciliate, mostly feeding on algae and bacteria! Clip 6: the same Colpoda as clip 2 but viewed with phase contrast illumination. You can see it engulfing a small algae! Clip 7: Aeolosoma worm Clip 8: more Gonium algae but viewed under phase contrast illumination! All videos were taken with my iPhone mounted on a BA310E Motic microscope with an @ilabcam adapter 🔬 References: Foissner, W., & Berger, H. (1996).
