ELI5: Why do snails move so slow?
gpt
Because they have no need to move faster. Their method of moving is efficient but slow - and as in loads of things, it's a trade-off that works for them.

Were they to move faster they'd need to produce slime at a much higher rate - and the slime is really clever stuff. It's very low friction at low speeds - you need to give it time to shear. Move quickly and you'll use a lot more energy.
