But oh, it gets worse. As is often the case with early medicine, some of the participants in the studies of electric fish were not what you would call willing.

Now, back to electric eels. The electrocytes of electric eels are arranged in stacks, each stack insulated from the next. Every stack of thousands of electrocytes acts as a separate “battery” that can generate voltages as high as 600 V. The separate stacks of cells then combine to give the electric eel the ability to generate a sizable pulse of electricity. Pure water is a poor conductor of electricity, but the waters where electric eels live have enough salt and other minerals to make them conductors. When an electric eel shocks the water, current flows out of the front part of its body, through the water, and back to the fish’s tail. Any other organisms in the vicinity will feel the stunning effect of this powerful current as it goes through them.

Electric eels, a relative of catfish, slink quietly about in the murky depths of the Amazon River, looking for ill-fated creatures on which to discharge their 600-volt weapon. We’ve known of the eel’s formidable hunting ability for decades, but the exact mechanics have proven difficult to study (you try capturing an 8 foot-long living taser and bringing it back to the lab—it ain’t easy).

The electric eel is found in the middle and lower Amazon basins of South America. They have no scales. The mouth is square, and positioned right at the end of the snout. The anal fin extends the length of the body to the tip of the tail. This fish lacks dorsal, tail & pelvic fins and swims by undulation of the anal fin. Electric eels have a vascularized respiratory organ in their oral cavity. These fish are obligate air-breathers, rising to the surface every 10 minutes or so, the animal will gulp air before returning to the bottom. Nearly 80% of the oxygen used by the fish is taken in this way. It feeds on frogs, fish and crustaceans.In a , researchers have worked out how six different groups of electric fish evolved organs capable of generating electricity. All muscle cells have electrical potential, but in these six groups of fish, certain muscle cells evolved over millions of years into cells called electrocytes, which generate much higher voltages than ordinary muscle cells do. This enabled these electric fish, all native to the muddy Amazon River, to employ their active electric sense much like bats use echolocation: to detect obstacles and other animals in the dark.
