Zoochory is a method of seed or spore dispersal where animals carry the propagules. This process is vital for the reproduction and spread of many plant species, allowing them to colonize new areas and maintain genetic diversity. Animals can facilitate zoochory in several ways, broadly categorized as endozoochory, epizoochory, and synzoochory.

Endozoochory occurs when animals ingest fruits or seeds, and the propagules are then dispersed through their feces. The digestive tract of the animal can sometimes scarify the seed coat, improving germination rates. Many fruit-bearing plants rely on this mechanism, attracting animals with nutritious and palatable fruits.

Epizoochory involves propagules adhering to the external surfaces of animals. This can happen through sticky seeds, burrs with hooks, or seeds that become embedded in mud or fur. As the animal moves, these propagules are carried to new locations.

Synzoochory is a dispersal method where animals actively cache or bury seeds for later consumption, but some of these stored seeds are forgotten or not retrieved and subsequently germinate. This is common in animals like squirrels and jays.

The effectiveness of zoochory depends on the animal's behavior, diet, and the characteristics of the propagules. It plays a significant role in shaping plant communities and ecosystems, influencing species distribution and long-term survival.
