|Feather duster worms, on the underside of a huge rock, at the top of the tide pool.|
|These are big worms, well over an inch wide at the crown. There are hints of others farther back, where the sun hasn't reached; they look almost purplish-black.|
|Two tubes at the far end, with a few more deeper down, in the shade.|
I touched one tube; the worm in it disappeared instantly and didn't reappear while I waited.
About half of the visible worms were striped; the rest were dark red.
