During a big minus tide, this long sandbar was exposed, with over a hundred alive adult Strombus alatus on it. When the tide recedes this much, they actually dig their way up out of the sand and prop themselves up as if they are enjoying the fresh air!

It seems risky to me, considering there are gulls and presumably raccoons and so on that might view them as a tasty meal.

And there were no juveniles at all that I could see, unless they remained hidden in the sand.

When the tide lowers enough to expose the sand bar (during a -0.6 tide,) the fighting conchs dig themselves up out of the sand, hop around a bit using their operculum, and then prop themselves up on the edge of their shell, as if they enjoy having the fresh air on their bodies!

Very odd behavior that I find it hard to make sense of.

They always do this however.
