This lecture series is terrific. I have one question: If there is internal water pressure, how come the gut (the greenish circle in the diagram) manage to remain open? Water pressure must flatten it, which will make it useless.

That is a great question. While the intestine (which is most of the nematode gut) lacks musculature, there are muscles associated with the mouth/pharynx and the anus. So, solids and fluid can be pumped into and trapped in the gut (creating its own resistant pressure). The movement of the animal is necessary to keep food moving through the digestive tract. Hope that helpsz

Interesting custom wood microscope mirror stage. Can you share the design scheme or link to buy?

Great little video. There aren't many readily available lectures outlining the basics of bacterial phyla.

Great video! Most of the videos I’ve seen on KZbin make it seem like even the person explaining doesn't understand the difference between these two. I finally have a clear idea of what the differences are. Thank you!

Can you tell me how to attach that other rod so that it "flies?"
