Those aren't lips

This is a paramecium undergoing fission - a primitive type of asexual reproduction. This little guy lives his entire life as a single cell. when he gets too big and conditions are right, he makes an exact copy which goes off and does its own paramecium things.

 

Most of my students see lips, which is fair. I don't even mind if they don't see the paramecium. I want them to see that there is more than a glowing screen. I want them to try and think through what it would be like to live as a single cell...even for just a moment.
