The tube-dwelling rotifer Beauchampia with eggs

#1 Post by tlansing » Sun May 15, 2022 12:05 pm

I have posted on the rotifer Beauchampia previously, but I was looking at a coverslip that had been floating in an old dish of pond water (for probably a couple of months) and I found this one. The most interesting thing about this particular individual was the presence of two eggs in the tube along with the parent rotifer. Also attached near the base of the Beuchampia was a bdelloid rotifer but it is out of focus. The Beauchampia was irritated by a algal colony (with a mucilaginous coat), so it kept waving its corona of cilia and contracting into its tube home to avoid it. The two antennae are clearly visible as the rotifer extends out from the tube. It was fun watching this one!

I've never seen anything like this before.
It's very interesting.

I didn't know about this Rotifer and didn't found much information. Do they build a shell to live in?

Amazing video by the way...

Hi sinabro and Javier: Thanks for your comments on the video. Javier, this rotifer does build the tube in which it lives.
