One example of regeneration in nature is the ability of starfish to regrow their arms if they are damaged or lost. This process, known as autotomy, allows the starfish to regenerate the lost body part by triggering cell division and tissue repair.
Regeneration, if your talking about the process thru which an organism can regrow a damaged or lost body part by using cell division, can be used by starfish and an octapi and other organisms but not every.
Easy, it happens when a part of the body of an animal(the parent) is cut off and that part turn into another animal of the SAME kind of it's parent it's already called regeneration. Examples of such animals is a starfish or seastar (scientifically).
The phylum that is known for its remarkable ability of regeneration is the Phylum Echinodermata. This group includes organisms like starfish and sea cucumbers that have the ability to regrow lost body parts, such as arms, through a process called autotomy.
Regeneration. It is the process by which an organism is capable of restoring a lost or damaged body part, such as a limb or organ. This ability is seen in some animals like certain species of salamanders and starfish.
Regeneration in animals involves the ability to regrow lost or damaged body parts. Some animals, like starfish and planarians, can reproduce through regeneration by regrowing a whole new individual from a fragment of their body. This process typically involves specialized cells called stem cells that have the ability to differentiate into various cell types to rebuild the lost tissue or body part.
Regeneration
a starfish is missing a few body parts like fins and tails
Starfish are able to reproduce sexually and asexually. Asexually, the starfish are able to reproduce if part of the starfish's arm is removed, along with part of the central body. From that detached piece, another starfish will form, along with the first starfish regenerating a new arm where the original arm was located.

Regeneration
Fragmentation is the ability to regrow body parts...like with a starfish, or worm. Only the worm will grow two butts, so the second half will die. But with the starfish as long as you cut through part of the nucleus (Middle) it will regrow the missing parts.
