Juvenile Basket stars or segmented worms??

These funny segmented worms?? were wrapped around a couple of soft sea rods. Depth around 50ft/15m mid-reef. Bequia in St Vincent & the Grenadines. Any ideas??

Hi Polly & welcome to Wetpixel --

Do you have any close ups of the "worms"? They're more likely to be entwined basket stars/brittle stars or solenogastres (unusual shell-less, worm-like molluscs) than polychaetes. The circular orange area with triangular segments in the middle of the closest branch looks like the disc of a brittle star.
