Vorticella at 40×

What you see

At 40× you see the whole animal and how it moves, but little inner detail.

This loop is the 0:28–0:53 part of a 1:22 recording; the full recording is on Commons.

Points to check against your own sample:

• Often in clusters on plants, debris, even on the shells of small crustaceans.
• Bell-shaped cell with a lip of cilia that draws a current toward the mouth.

Full description and look-alikes: Bell animalcules.
