Hi all.

Medusa worm.

 

[Kieko250]

Good or bad?

Medusa worm for sure. Good clean up crew, it's actually a type of sea cucumber believe it or not! It will get bigger as it ages. I think they max out at like 2'.
Very lucky hitchhiker! You don't see these too often.

Hmmm. was thinking tube worm

ALTHOUGH MEDUSA VERY SIMILAR BUT I THOUGHT WEDUSA HAS 4-6 DISTINCTIVE FEATHERS.

Medusa:

Hi all .. found another white worm looking tube. Any ideas?

 

[Mr_Knightley]

Does the tube appear to be made of sand? If so, I would assume it's a Spinoid worm, completely harmless and cool biodiversity.

I Can’t tell. Can’t see the head either Will try to get a better pic of it moves closer
