Charles Darwin was fascinated by earthworm behaviour. He experimented with different types of food, placing the food on pieces of tinfoil to make sure the earthworms did not accidentally come upon the food by burrowing from below. He recorded that they preferred wild cherry and carrots, that raw fat was preferred to raw meat and that, “judging by their eagerness for certain kinds of food, they must enjoy the pleasures of eating”.

He tested their senses by exposing worms to lamps or candlelight and their sensitivity by holding “a poker heated to dull redness near some worms”. Earthworms do not have ears, but Darwin still tested their sense of hearing. He used a metal whistle and had his son play his bassoon loudly. Darwin even shouted at the worms but found that, if care was taken that his breath did not strike them, they were indifferent to noise. The earthworms also remained quiet when set on a table close to a piano, which was played as loudly as possible. That all changed, however, when the earthworm pots were placed on top of the piano. Darwin noted that earthworms are extremely sensitive to vibrations....
