This was amazing. At our local inlet i snapped these little guys just this week. Not as professional, but amazing nonetheless. The sound of their little legs is amazing! http://www.youtube.com/watch?v=YR6jbuC3iBw&feature=youtu.be

Dear STEVE, VERY INTERESTING AND GREAT PHOTOGRAPHY..........I ACTUALLY SAW 2 CRABS GOING THE WRONG WAY, WHY? GPS FAILING? BATTERIES LOW? LEFT THEIR GLASSES AT HOME? I AM A NEIGHBOR OF LYNDY AND HEINZ HERE IN VERMONT AND HEINZ JUST TOLD ME ABOUT THIS. BEING A LONG TIME RESIDENT OF EASTERN LONG ISLAND, NY, I'M FAMILAR WITH HORSESHOE CRABS SO I FOUND THIS VERY INTERESTING. WE ALSO HAD SMALL CRABS SIMILIAR TO THESE BUT CAN'T THINK OF THE NAME OF THEM. THANK YOU, BUD THOMSEN

In response to Warren A. Hollier and others. These kinds of mass aggregations usually happen every 5 to 7 years. Smaller ones happen almost yearly. The crabs come down of the hills as high as 1200 to 1500 feet up and go to the sea to swap shells and spawn. They return to the same beaches they were spawned at and follow the same trails their ancestors followed. So, there are different trails to different beaches. They will crawl over, around, through anything that gets in their way. It's a totally amazing spectacle. Did you happen to notice that all the crabs seemed to have about the same sized shell? Therein lies the issue for the poor hermit crab. The larger shells are getting harder and harder for them to find and as they grow they have no means of upgrading to a larger shell. It is unknown what kind of affect this is going to have on them in the long run. In the Virgin Islands they are called soldier crabs because of this determined march to the sea.

Looks like an evening at Sam's Club.... (fantastic, though - the Hermits are beautiful!)

Were they migrating or escaping from something? Does this happen every year on cue or is this a cyclic happening every 10 years or so. Maybe we had better study this a little deeper. What unusual changes are happening in the waters around the island. Is this a response to a man-made accident (chemical or radioactive)? Is this a breeding event like salmon spawning? This is 2012 you know:)

Wonderful! Steve - Did the crabs attempt to climb your legs? Can you re-submit the video without the music? I too want to hear that marvelous crabby sound partly because I just do and partly because our satellite feed here is lousy and the video keeps jamming and the music lurches. thanks :)

So, where are they going? Would like to have seen video of the cabana where the free drinks were being served to these pilgrims.

Fascinating! Who would have thought there could be so many in one place? And where are they going to?

Fascinating! But why did the filmmaker choose to add music? I found it distracting and was disappointed that I could barely hear the sound of the crabs. To me, that's part of the story.

I remember as a kid camping on Cape Hatteras (the 1950's) watching the beach suddenly come alive with crabs one evening. We had to put our feet up onto the picnic benches to keep the masses from crawling over them. Not as many as shown in the video but every square inch of the beach was covered by them. It's a sight I'll never forget.

This is great! It would have been better without the loud soundtrack, just the ticking of the crabs would have been superior.

George! Where's Jimmy! Does anyone have any idea why they do this?

Fantastic video! Where was the photographer standing? This is the making of a good horror movie: can you imagine having fallen asleep on a beach and waking up to this?

Are they running from something or running to it? It looks like a great, religious pilgrimage.
