Probably the most interesting thing about these penguins, is that they have to cooperate as a group in order to survive. Those that remove themselves from the pack die. When the harshest weather sets in, they act as a single organism and huddle together in a manner that assures survival. Each penguin depends on the group and each mate utterly depends on the other for survival of the egg. The female must transfer the egg to her male mate, who in turn depends on that single female to trek 70 miles back to the ocean and then 70 miles back to the nesting ground to give him and the hatched baby food (he's starving all the while). The reason for this, is that production of the egg, saps the females strength to the point where she must abandon her egg to her mate in order to get food. All food sources are back at the beach which is 70 miles away. In the meantime, her male mate begins starving and depends on her to return with some food.
The original poster talked about the emotions of the whole thing, I just think it's interesting how the survival thing plays out. Only the group survives. Individuals die.
