The life lines of 2 hermit crabs intersected with ours at the beach today. My son found both. After they reluctantly posed for me, I returned them to the incoming tide.
If I am not mistaken, the one above was occupying a Melongena corona shell. The other one was a big, hairy, mean-looking guy (or a gal), but it would rather stay in the safety of its shell than come out and crawl across the sand. I believe the 10-cm long shell it had adopted was a tulip shell (Fasciolaria sp.).
