What you see

This loop is the 1:01–1:26 part of a 2:28 recording; the full recording is on Commons.

Points to check against your own sample:

• Bell-shaped cell with a lip of cilia that draws a current toward the mouth.
• A single, unbranched stalk with a contractile thread inside: Vorticella. Branched colonies: Carchesium, Zoothamnium (contract) or Epistylis (does not contract).

Full description and look-alikes: Bell animalcules.
