Epizoochory

the transport of the seeds or fruits of plants on the surface of animal bodies (hairs, feathers, paws). In the course of plant evolution, the following adaptations have been developed to ensure epizoochory: mucus secreted by cells of the seed coat (flax, plantain, many crucifers), sticky glandular hairs on fruits (twinflower, nightshade), holdfasts and thorns on fruits (alfalfa, hound’s-tongue), calyxes (marigold, Labiatae), and lemmas (Tragus).
