Researchers at Clarkson University in New York and Ben-Gurion University in Israel have found snails can produce electrical energy, Engadget reports.

The secret lies in hemolymph, snail bodily fluid that’s comparable to blood. “A pair of Buckypaper electrodes were charged by the electro-chemical reactions in the slow-moving invertebrates ‘hemolymph,’ its equivalent to blood,” according to Engadget. The researchers break it down further in the abstract of their paper:

The “electrified” snail, being a biotechnological living “device”, was able to regenerate glucose consumed by biocatalytic electrodes, upon appropriate feeding and relaxing, and then produce a new “portion” of electrical energy.

If that’s not bizarre enough, snails potentially could sustainably power listening devices for the Department of Homeland Security, Engadget notes.
