Worm ID

[olga]

Anybody knows what kind of worm this is? I checked hitchhiker thread, and can't find worm which looks like this. Is it harmful to the reef/fish/inverts?

looks like a flatworm of some kind. Check with some marine biology sites.

I did had a look on other marine sites, so far my research was unsuccessful.
Its not flat worm, his body is round, black, he is about 10 inches in length and have like a white crown on his head.

I can't believe nobody here had this hitchhiker before. Surely somebody must know. Maybe its not a worm, and some kind of marine baby snake?

Peanut Worm or Vermetid Snails?

Thank you, Reefnut. I can't see its peanut worm, nothing like that. Picture of the vermetid snail, reminds me of some male part of anatomy ;-) (sorry)
Will continue my research, to find what this critter actually is. I can't take better pictures of this worm now, as he disappeared again in the rock hole. When he will make an appearance again, I will do.

That does not sound like a Vermetid Snail... it does sound & looks like a peanut worm though. Do a search for peanut worm and find some other pictures. Maybe yours is just darker than mine or something?

Do the white markings on the one end look like the " zig-zag " pattern on this one and the other end can be big or streched out long. If so, then its a ribbon worm, Phylum Nemertea

It does have zif-zag pattern. Thank you so much, Dogstar. This is definitely the one. Will read further on about it.

I just got in 200 lbs of LR and found two of those ribbon worms. Both were dead unfortunately. Pretty kewl.
