    The Dive Guide told us this is a Christmas Tree Worm. But it is not like any I have ever seen in that it is:
    on sand not coral,
    about 20 times larger than any christmas tree worm,
    has branches not double helical shaped.

    Hard to tell without knowing the location. It could be a worm or a sea cucumber.

    In the fjord at Tufi in PNG. About 35'. Daytime. 87F water. Almost zero current.

    Looks like a sea cucumber. I don't have a PNG I.D. book so I'm not sure of the name.

    Sarlacc... don't fall in. You'll be digested over a 1000 years, and find a new definition for pain and suffering...

    Sadly, while I saw you were kidding, I had to look it up to understand the reference.

    Yep, a burrowing cucumber cf. Neothyonidium magnum.
