Worm ID

I saw this worm bouncing around on the bottom in around 4 metres of water in Long Bay, Malabar, a south eastern suburb of Sydney.

I'm guessing it is some species of nemertean.

This - or something like it - has come up before. If it's really the same thing then it's the proboscis of a giant echuroid in the genus Ikeda. Here's the link for the previous post - http://wetpixel.com/forums/index.php?showt...20worm&st=0

Nemertinator will be happy to tell me I'm wrong if it's a nemertean.

Sorry to be slow on this - just cleaning out old mail.

I would not have guessed echiuran proboscis on my own , but yes that is clearly what it must be. Definitely not nemertean
