When I was a young kid I once found a dead animal and my grandfather taught me “how to see the bones” by placing the lifeless creature on an ant hill and letting the little buggers have a smorgasbord. I found the whole procedure both fascinating and nightmarish, Practically speaking, it’s a great method for cleaning skulls — and ecofriendly too I might add. I figure crabs probably do a similarly good job, and that seemed a bit more Viking for some reason (I remember someone being eaten by crabs in the movie, The Vikings). Enjoy! 😛
