Hi Paulo,


It looks like it could be a corophid-like amphipod or tanaid crustacean, al=
though very large if your 10 centimeter size estimate is correct. The wood =
piece looks like a mucus/detritus tube and if you zoom in on the picture th=
ere appears to be a pair of antennae above the yellow structures which also=
 may be a pair of modified antennae? I would be interested to hear what oth=
er folks think.


Thanks,


Dave

Hi everyone,

A colleague doing annotation from ROV images observed this animal (black
circle) and we dont what it could be.
It seems to use the wood piece (?) to live as a hermit grab. I supposed the
yellow structures could be in the anterior region but if its the case it
moves backwards. I think its not a polychaete but i have no idea what could
be. It seems to have about 10 centimetres (maybe more).

The photos were done from 520 and 575 m depth in l=92Astrolabe Bay Papua Ne=
w
Guinea.

Some idea???

Thank you,
Paulo
