"Some choanoflagellates are non-motile, meaning they spend most of their life not moving around. Instead, they just stick themselves to a nice, sturdy surface and grab whatever food passes by. There are also motile choanoflagellates, which move around with their flagella, but in kind of a weird way. You see, other flagellates use the twisting rotor movement of their flagella to pull them around the microcosmos, but choanoflagellates use their flagellum to push themselves through the water."
