Et Cetera

To hungry pike as well as hungry humans, carp can be a most satisfying meal. But the freshwater fish has a way of fooling at least its piscine predators. According to researchers at Lund University in Sweden, when pike are placed in carp-filled ponds, the hunted fish begin to bulk up on food in the water until, after 12 weeks, they are simply too big for the pike to swallow. But the bigger carp expend more energy swimming. Once the pike threat is gone, the carp should revert back to their slimmer shape. Call them the Arnold Schwarzeneggers of the deep -- at least for a while.
