From the breeder's site:
"I'll call this the 'Cannibal Corn', though since it's dead and frozen, naming it is hardly a concern. I found this baby amelanistic corn this way in its individual shoebox cage, so it was not due to a struggle with a cagemate. I hadn't fed it recently either, so the centrally located lump was not a mouse. Maybe that's where its own rear end was curled (doubled over), because its tail was obviously folded over."
I've heard of ophiophagy/cannibalism in corn snakes before, mostly from herp horror stories where amateur owners housed two reptiles one day and returned to find one fat one the next, but this is something else! I guess corn snakes just dropped a couple ratings on the intelligence scale.
