Seeds with impermeable seed coat, i.e. physical dormancy (PY) are capable of surviving the passage of animal gut with little damage to the internal structures.

The type of herbivores, seed maturation state and amount of seeds available can significantly affect the process of endozoochory.

Seed movement outside the parent plant community through the process of endozoochory often provides numerous fitness benefits to PY species.

PY seeds dispersed by endozoochory can establish long-term seed banks or germinate in a novel environment.
