stylish crustacean, part deux

crabswe hit the jackpot this weekend at the beach in duxbury - two handfuls of leopard print crabs including this spectacular whole crab. anyone have any good ideas on how best to preserve/display these creatures? I've seen bugs and butterflies with delicate pins thru them but I don't want to damage these shells. they're also too dimensional to just glue to a linen-covered board. I"ll let you know what I find out but until then, they're on my nightstand
