Handmine
From Tardis Wiki, the free Doctor Who reference
Handmines were used on the planet Skaro during the war that lasted a thousand years. They appeared in groups, and would take hold of and pull individuals underground. They resembled decomposing hands with an eye in the centre of the palm.
They were drawn to sound and movement. If a person was still but making noise, they would rise up from the ground to search for the target.
As a child, Davros found himself surrounded by handmines. Kanzo tried to help him, reminding him to stand still before being pulled underground. (TV: The Magician's Apprentice)
