unless it is shallow like shown they can and do pass right under me and I see them as they have already passed...there is not a ripple or any indication they are there...4-7ft sharks can be more stealthy than a bonefish in 3ft of water...I also experience a certain terror when wading and having them surround me or track me...the huge bulls will be gathering in the next few weeks as the rainy season approaches...once they open the freshwater canal flood gates they will be stacked in the freshwater flow and ready to attack...some so big I duck down inside the canoe so they dont see me...my canoe is a little over 40" wide and I promise you the heads on these bulls is much wider than that...I will be taking pictures soon as it rains just before June
