New to me critter

#1 Post by Bschnitzer » Sun Sep 17, 2023 6:05 pm

The scale in the lower right is incorrect - should be 100 micrometers instead of 200. The video is slowed by 2x.

Thanks.

It's a double spiky bent sausage-thing.

This is two stylonychine ciliates (probably Stylonychia) in conjugation. They are exchanging gametes. :)

Had a busy day with a drop of water pond. Can someone please help ID this organism?

@MitchW It's a Stentor. Identification to species would begin with a clear view of the macronucleus.
