Look closely and you'll see the south end of a 4-foot bonnethead shark that swam into very shallow water (less than 12 inches) to feed on St. Simons Island, GA, last week. A few moments later, a 5-footer ventured into the same shallow water. I saw small sharks feeding in the same spot everyday right as the incoming tide starting washing over a sandbar. Remember that when you see feeder fish jumping and birds diving in the water, the food chain is doing its thing. That means it is time to get out of the water for a while.
