Mitchell Posted April 20, 2011 Share Posted April 20, 2011 I have these things growing on my rocks and now they are showing up on my snail shells. What are they? I don't think they are a tube worm because nothing comes out of the tubes. I was thinking they may be sea squirts, but I am not sure. Link to comment Share on other sites More sharing options...
TheGooseWhisperer Posted April 20, 2011 Share Posted April 20, 2011 if the tubes are hard i believe they are encrustung snails. they let out slime lines and haul in the bits the catch. i have hundreds of them, but my newest emerald crab has put a big dent in the population.
