White spots on Trochus snail?

[Nando]

One of my Trochus snails has a bunch of white spots on it. Anything to be concerned about?

you have worms on snails lol. The white things are spirorbid worms. Harmless filter feeders. They're just along for a free ride ;)

Very interesting and super cool. This kind of symbiotic relationship is the reason I got into reefing :)
