Another bivalve victim

The foot being ripped of is not how the foot would be lost, either David's 
explanation of ripping/tearing of tendons or of the fishing line cutting into 
the flesh leading to infection and then gangrene are how I had been led to 
believe the foot/leg could be lost from fishing line. I'll see if I can find 
some sort of reference for it but gangrene makes sense to me.

Cheers, 
Chris
