This is a quiz, and then I have a serious question.

1. Who knows what this is? (Answer in post below/see larger pic also) It was on the beach at a very low tide in Humboldt Bay last June (2011).

2. (The serious question) What purpose does it serve? Why do they make them? No, I don't have the answer for this one. . .

Collar Specs - Canon 40D, f7.1, 1/80 sec, iso-200, +0.3 exp bias, 300 mm (100-400 IS) full frame, handheld.

Critter specs - 40D, f6.3, 1/60 sec, iso 200, 135 mm, 67% of FF.

The photo above is of a moon snail collar. There were eight moon snails that we saw this time, and three the next morning. Moon snails can get up to six or so inches across. I am holding a small one in hand that has closed its operculum.

Fun critters to play around with.

It looks like a parking meter pole collar?

It's an egg case. The eggs are imbedded in the jelly-like collar. Try Googling Polinices (the genus of snail) and collar or egg case for more info.
