The seeds of grapple plants are dispersed long distances because the numerous hooks on their capsules cling to the feet of passing animals.

The South African grapple plant, a low-growing creeper, relies on its seeds being trodden on. Its capsules have arms ending in hooks that are so sharp, so strong and point in so many directions that when the foot of an elephant or rhino descends on one, the hooks fasten into the sole and the capsule stays there, step after step, until the arm wears so thin that it breaks and the capsule with its seeds breaks away. (Attenborough 1995:23)
