Examples of simple animals capable of regenerating from multiple pieces include Hydra and Planaria. When cut into pieces, each fragment has the ability to develop into a fully functional organism.

Several simple animals possess the remarkable ability to regenerate from fragments, with each piece capable of developing into a complete organism. Planarians, flatworms belonging to the Platyhelminthes phylum, showcase exceptional regenerative capabilities. When cut into fragments, each piece can regenerate into a fully functional planarian. Hydra, a freshwater organism from the Cnidaria phylum, can regenerate from small tissue fragments, forming complete individuals. Sea stars (starfish), members of the Echinodermata phylum, can regenerate from severed arms, with each fragment regrowing into a new sea star. These examples illustrate the extraordinary regenerative potential found in certain simple animals, enabling them to recover from injuries through the formation of new, fully functional organisms.
