Q. Are you afraid of any particular fish? A. I am afraid of most of them. This might sound like a strange answer, because most people think I am fearless. But it is important to have fear. Fear makes you pay attention to what you're dealing with. Several fish that I deal with have very sharp teeth, like the Goliath Tigerfish in the Congo or Bull Sharks. If you don't pay attention for a second, you can get badly injured. So I do my research beforehand. But there is one fish that is particularly dangerous — the Electric Eel in the Amazon. It doesn't look very dangerous, with no big teeth, no spikes on its body; it's not muscular too but a big one can deliver over 500 volts of electric shock. If you touch it in murky waters, it can paralyze you, leading to drowning.
