Anyway, I just searched it, thinking that someone else might have an idea, and it turns out that the biological explaination is that they’re not worms, but legless lizards.

Maybe the sand is the opposite of a non-newtonian fluid, is solid at rest but becomes basically fluid with vibration
Though I imagine sand would naturally behave this way if it isn’t packed too densely
