Another diatom this time. Striatella unipunctata in girdle view. These cells form chains with adjacent cells often attached by the corner as seen at the top if this image.

In the Bay 3 July 2007
Since I wrote about marine cilliates in my previous post, I thought I'd try to find some for this edition of In The Bay.
This is a group of Vorticella or Vorticella-like stalked cillates. As you watch the movie you can see the feeding current they are creating with their cillia. About 21 seconds into the movie (6 seconds from the end) the whole colony retracts. This is a defensive mechanism and occurs extremely fast.
