These are single-celled organisms called stentors, and because of their shape, they are also known as trumpet animalcules. This species is called stentor amethystinus and they can reach a size of a couple of millimeters — making them some of the largest known single-celled organisms in the world. #MicroscopicMonday 🧫🔬 by My Microscopic World | Science Channel

It may have been destroyed when filamentous algae were added to the slide, but that doesn’t mean it’s waving the white flag. You see this big blue chunk attached to the stentor? This chunk is going to regenerate into a whole new healthy stentor. #MicroscopicMonday 匿  by @tardibabe/IG | Science Channel | Facebook
