the distribution of fruits and seeds by animals. There are three types: epizoochory, the transportation of fruits and seeds on animal surfaces; endozoochory, transportation in animal digestive tracts; and synzoochory, distribution while animals are storing fruits or seeds. Correspondingly, plants are divided into epizoochores, endozoochores, and synzoochores.
The fruits or seeds of epizoochores have catches (small hooks or spines), mucus, or sticky substances—for example, marigold, stickseed, plantain, and mistletoe. Endozoochores have juicy fruits or seeds with fleshy appendages (arils) that when eaten by animals pass through the digestive tract not only unharmed but sometimes with improved germinating capacity—for example, cherries, honeysuckle, pomegranate, and spindle tree. Filberts, pine nuts, and the caryopses of grasses are all synzoochores. Ants frequently distribute fruits and seeds; this is called myrmecochory.
