Lamma Island - Snail Army

We were crossing a sandy beach when I stepped on some tiny dead snails.  There were a lot of them, and they looked a little odd, so I looked closer.  Then I realized why they looked odd - they were all pointed in the same direction. 

And they were moving - they were alive!  It was just that it was low tide, they were exposed to the sun and their shells were dried, that’s why they looked dead.  They seemed to be crawling towards the water - that’s why they were all pointed in the same direction. 

I estimated that there were roughly 500 of them per square feet.  The sandy beach was very flat, and quite large, perhaps as big as 200 feet by 100 feet.  That means there were 500 x 200 x 100 = 10,000,000 snails on that beach.  That is more than the population of Hong Kong.  Truly awesome, isn’t it?
