almost looks like a sweeper tentacle from a coral, may just be a part of a larger organism not the organism itself, but I'm definitely not an expert so hopefully others will chime in
Def not a peanut, it really looks like loc-line. Or just little tiny balls all stuck together
Well I'm glad I'm not alone on this battle my Lfs says the closest thing to it is a fireworm. I'm not buying it at this point. Do you see yours often?
Looks similar, but not the body on mine looks like a string of marbles, yours looks like it has more of a body.
