This may sound stupid, but I relate it to the countless shark "incidents" I have had over the years. I always feel that although, I don't think the shark intends on eating or biting a diver, one really can never know for sure. They are animals in their habitat and are subject to bouts of extreme hunger, mood elations, territorial postures, etc... My father introduced me to spearfishing and he always stressed to never underestimate a shark. Among many of his advice was that "Un tiburon es un tiburon."
Anyhow, I was watching an animal program yesterday concerning a lion pride in Africa. This particular pride had many juveniles and adolescent lions that had not honed their skills yet. Most of the hunters were three mature females. The two main lions were off marking their turf. In any event, the pride had gone almost a week without eating and they were desperate. Desparate times calls for desparate measures and the two top hunters attacked a 3 ton Hippo. Obviously, they hoped for the rest of the pack to assist in taking the hippo down, but most of them hesitated and did not participate. As the mature females were gnawing at the Hippo's back, it reared its head and grasped one of the lions by the skull. It focked it up good and nearly killed it. What normally would not be a quarry for these lions became one under hunger and duress. I wonder how many times this has occured with sharks in the wild...
