Checkered Periwinkle
There's a little black snail inside that checked shell, but he's quite shy and wouldn't show much at all. These were rather abundant, although many of the shells were no longer inhabited by periwinkles at all, but rather the adopted home of a legion of tiny little hermit crabs.

''Littorina scutulata'' is a species of sea snail, a marine gastropod mollusk in the family Littorinidae, the winkles or periwinkles.

As for species introductions, yes that sea otter surprised me as well, but then again, the site knows 4,000 species...out of....2 million.
