Since Evan was able to help out this week, we cleaned and counted the snails I currently have in the seawater table. When he was cleaning one of the cups, he caught a whelk in the act of eating! It had its proboscis extended into the gape of a mussel and it looked pink at the end, as if it were sucking up pink mussel flesh. I was so excited to see this I took several pictures. It was not easy to get it in focus, but see below for the best photos I could get.
