Cable bacteria are tiny little living things that look like long and skinny wires. They are found in the mud at the bottom of the ocean or in lakes and rivers.
Now, just like how we need food to survive, cable bacteria need to eat too. But instead of eating pizza or apples like us, they eat chemicals like hydrogen sulfide which is found in the mud they live in.
But here's the really cool part: these cable bacteria are so useful to other living things around them! When they eat the hydrogen sulfide, they release electricity into the mud which helps other tiny living things grow and live. It's kind of like a battery that never runs out of power!
Scientists are still studying cable bacteria to learn more about how they work and how they can help the environment. Who knew such tiny creatures could be so amazing!
