This has happened to me before, but yesterday was the worst. I was out on the mud flats at low tide yesterday early evening. I picked up several kings crown conchs that appeared unoccupied- and I swear I looked hard. But when I got home and started submerging the shells in water, hermit crabs came out or peeped out of about 5 of them. I took them down to the beach by my condo, but it is gulf side, and I don't know if they will survive. What is the best way to save hermit crabs you accidentally bring home?
