Strange tendril
 
Hi Ron,

It looks like two blades (leaves) at the end of a long tendril that can stretch 12" easily from the liverock. Here are a series of images. What is it?

And is it anything to worry about? ;)

Hi Marc,

It is the proboscis of a bonellid echiuran worm. See [url=http://www.rshimek.com/odd_critters.htm#Echiuran%20Worms] here [/url] for some more information. The worms are harmless detritivores.

Thanks Ron. I had one before in my 55g that was brown, but this one is green and larger. Thought I should double check. Thanks!

I really think that is in the sponge family, myself.

Hi whodah,

Marc's correct, what you have taken an image of is a piece of sponge.

Abominable Reefer 08/17/2004 11:09 AM

Thanks Marc and Ron. I have the same thing in my tank and it's been freaking me out.

whodah 08/17/2004 12:27 PM

cool, i did not know that sponges stretched out like that! the most i've seen him stretch out is about 6".

i swear he was 'lassoing' some neighboring paly frags and dragging them closer, heh!

Bill.
