fungi

Fungi are in between animals and plants. Their cell walls are made of chitin—a substance never found in plants—which makes them more like insects.

Even so, other scientists would like to see more evidence before they are willing to accept them as a form of language. Other types of pulsing behaviour have previously been recorded in fungal networks, such as pulsing nutrient transport – possibly caused by rhythmic growth as fungi forage for food.

Mathematical analysis of the electrical signals fungi seemingly send to one another has identified patterns that bear a striking structural similarity to human speech.

Previous research has suggested that fungi conduct electrical impulses through long, underground filamentous structures called hyphae – similar to how nerve cells transmit information

That makes fungi the largest known living organisms in the world.
