ok what is this demon worm?

[organism]

This one crawled out to eat some dead pods when I was treating with Interceptor to get rid of some predatory pods. It's about 3-3.5" long and swims faster than my clownfish like baby bristleworms do... When I first tried to catch it it took off so I just siphoned it out the next time it came out. It has legs under the tentacles, and the legs shoot fireworm spines in and out like a switchblade when it gets poked. *** is this thing?

Video of it swimming like crazy in this mug, it started off playing dead at the bottom.

I thought I would be helpful and dig around and give you the name of that nasty looking critter, after 1 1/2 hours I am throwing in the towel. Sorry man. I will keep an eye out online and on this thread. Good luck

It could be a fire worm but I'm not sure. Member Cloak will see this thread and he will certainly have an answer for you. But bottom line is KILL IT :hammer:

Is that not just a fat bristle worm?

 

[Dkuhlmann]

Ben I don't think so, I'm pretty sure it's one of the bad worms.

Got anything from off the coast of Florida?

Have a look here. http://chucksaddiction.thefishestate.net/hitchworms.html

This is a fireworm. Whatever it is, it isn't that. It's not a eunicid, either. That covers the two harmful species I know about.

 

[davocean]

Syllid worm possibly.

Nereimyra sp.?

I did actually, I got some Gorgonians and zoanthids from a farm down there a few months back, great find!

It really looks like Nereimyra punctata, seems like they eat pods and detritus?

 

[KafudaFish]

Yeah when I first guessed I found a distribution map showing that species off the Atlantic coast of Europe in deep water and figured nope.

I found another which showed records off of Florida and up to NC so who knows.

It is an interesting looking demon though.
