This video has been posted all over the Web, but I thought it is still pretty impressive camera work by Steve Simonsen.
Have only seen a few hermit crabs in a tank at the pet store. This is pretty overwhelming seeing thousands upon thousands of the hermit crabs scuttling towards land. 🙂
And did you know this interesting fact?
Several hermit crab species, both terrestrial and marine, use “vacancy chains” to find new shells: when a new, bigger shell becomes available, hermit crabs gather around it and form a kind of queue from largest to smallest. When the largest crab moves into the new shell, the second biggest crab moves into the newly vacated shell, thereby making its previous shell available to the third crab, and so on.
