the tube isnt visible in the photo - thats a krill food piece.
the photo is real close - the white spiky thing is twice the size on my screen than in real life (1280x1024 res)
it does retract
it doesnt wave around like my other feather dusters - just kind of sits there making me think its not...
directly under the word "moment" 2/3 of the way down the image - the white spiky kind of thing - it appears to have a tube attaching it to the rock.
I see no anenomes anywhere in the image - or am I blind ?
