Which animals have developed capacity of regeneration?
1 Hydra , Starfish
2 Plasmodium
3 Earthworm
4 Spongilla
Explanation:
The hydra and the planarian flatworm have long served as model organisms for their highly adaptive regenerative capabilities. Echinoderms (such as the sea star), crayfish, many reptiles, and amphibians exhibit remarkable examples of tissue regeneration.
