Alga. Lacrymaria video.

[Charles Krebs]

Haven't been around much lately (or at my scope ).

Wow!... lots of new images to look at, and new members as well. Need to try to spend some time here tomorrow.

I did have a look at an old sample jar that was starting to produce some fine algae. Took a few shots (alga only).

Really interesting was the numbers of Lacrymaria. In the past I've posted a number of still images of these, the latest being here.

The most bizarre thing about Lacrymaria is their unbelievably great neck extensions, and the rapid sweeping head movements as they hunt for food. Here's a video of six Lacrymaria. The quality is "so-so" ... but if you have not yet been fortunate enough to see them when they are really active it might be worth a look. (20Meg MP4 file)

Best video of Lacrymaria I've seen.

Do they have a mouth at the end of their neck? A sticky blob?

Awesome.

What did you use for a camera?

Amazing algae shots. Such detail. And I have missed your videos. The first time I ever asked you about Lacrymaria, these are what I saw. I have not found any since and was getting them confused with Litonotus. But that first time, I was not sure of what I was seeing. It seemed impossible that anything could do that with a body part. LOL

Love those algae shots, especially the last one. The lighting and colour is spot on.

Donw,

What did you use for a camera?

Canon T3i (600D) for both still and video.

Charles, I have been meaning to ask, have you decided if the T3i has second curtain shutter sync or not, since the specs doesn't say?
