Look at this worm, I am pretty sure it is a Pacific Neopolitin Lugworm. See the little red bumps on the side, those are the worm's gills.
I cannot even begin to tell you the number of times we have been to the beach and seen the little piles of sand with holes in them. Never really paid any attention to what they were. I figured that they were an animal of some sort, it did not cross my mind that the beach literally had millions of worms!
The children dug for the worms and we were able to see the mucus lined burrow that the worm lives in. I think this is the acorn worm, (Saccoglossus kowalewski)
Ruby just could not seem to figure out that it was much better to keep her arms in her sleeves. I admit I did laugh when she fell in the cold wet sand and could not get up. It reminded me of Ralphies kid brother in "A Christmas Story".
