Good day,
I suggest these are built by amphipods (e.g. Dulichia), the size seems
to be similar. You may ask professor Alexander Tzetlin for additional
information for instance his group described similar rods from the White
Sea.

> Hi all,
>> Attached is a video frame grab of a field of tubes in situ from about 1000 m in Cook Strait. There's quite a strong current going past right to left but the tubes don't flex at all. The visible tube lengths would be about 150 mm. No tentacles to be seen. I was thinking Polychaeta, perhaps a large chaetopterid. Other suggestions welcome.
>> Cheers,
