Fragmentation is the process when an organism splits into fragments, and each fragment grows into a complete, individual organism. A fragment can develop into an independent adult. E.g. Reproduction of sea anemones, star fishes, and flatworms.

Regeneration is a modified form of fragmentation. Regeneration is the process of regrowth in organisms that allows for a partial or a complete regrowth of a damaged tissue. Planarian flatworms are capable of regeneration. Among the vertebrates, tailed amphibian (Salamanders) and certain lizards (geckos) are highly adapted to regenerate their limbs, tails, jaws, eyes and certain internal organs.

Fragmentation	Regeneration
Fragmentation is limited to invertebrates.	Regeneration is present in both vertebrates and invertebrates.
Fragmentation is a method of reproduction (E.g. Reproduction in star fish)	Regeneration can be used as a reproduction method or it can be used to regenerate lost body parts.
In fragmentation, each fragment produces new organisms.	In regeneration, when it is not for reproduction, the separated part does not grow into a new organism.
Fragmentation is more commonly seen in plants than in animals (E.g. Non-vascular plants)	Regeneration is more commonly seen in animals than in plants
