This process can be bidirectional, in which both parts of the animal regenerate their missing parts to form two animals (just like the hydra, planarians, earthworms and starfishes) or unidirectional, in which the animal loses an extremity but it just regenerates, without forming two animals (arthropods, molluscs and vertebrates).
