Some studies on roosters have suggested that birds can adequately regenerate some parts of the limbs and depending on the conditions in which regeneration takes place, such as age of the animal, the inter-relationship of the injured tissue with other muscles, and the type of operation, can involve complete regeneration of some musculoskeletal structure. Regeneration power in hydra was reported first by Trembly (1744). Earthworms, starfish, lobsters, snails, salamanders and scores of other creatures can produce their own replacement organs and/or limbs as well. “If there is a disturbance, be it a fire, a disease or insect outbreak, or direct human impact, we want to see that the forest can … 3.

Starfish that lose arms can grow new ones; sometimes an entire animal can grow from a single lost arm. All sponges possess a remarkable ability to regenerate lost parts. The fact that such a simple manipulation can restore healing abilities provides new insight into how the stem cells involved in this process are marshaled in animals.

Virtually all modern bony fishes can regenerate amputated fins, but the cartilaginous fishes (including the sharks and rays) are unable to do so. However, some recent results on gene loss indicate that this is not as universal a feature as is often supposed, as even vertebrates can lose genes during development, so it should not be assumed that all genes are always present 13 . Following activities show how animals help forest grow and regenerate. Some animals that can clearly and actively regenerate body parts are lizards regenerating tails and Planarians (Flat worms) That can be cut into pieces and then grow back. Still have questions?
