THE MUD IS ELECTRIC.

The article presents a study conducted by researcher Lars Peter Nielsen, who has found that the threads of electron-conducting cable bacteria can stretch up to 5 centimeters from deeper mud, where oxygen is scarce and hydrogen sulfide is common, to surface layers richer in oxygen. It mentions that bacteria produce compound in mud by breaking down plant debris and organic material; and in deeper sediments, hydrogen sulfide builds up as there is little oxygen to help bacteria break it down.
