Translucent tubes?

Recommended Posts

I noticed these things on my rocks the last couple of days. They’re translucent, and soft enough that they flow in current. If they somehow get detached they just float around, but they’re pretty solidly attached. These are the best photos I could get, it’s really hard because of how close to clear they are.

Are you sure they're hollow? 

 

Do they respond at all to touch? 

 

Best guess is either some kind of sponge, or dead bits of macroalgae.

I can’t say for sure if they’re hollow. They’re not very easy to see. No response to touch.

Probably a sponge. Doesn't look like anything harmful, whatever it is.
