Yes, salamanders can regenerate their tails and legs. See related link
Salamanders can regenerate lost limbs, as well as other body parts.RAWR
No. Mammals do not regenerate their limbs.
An example of regeneration is the ability of certain species of salamanders to regrow lost limbs. When a salamander loses a leg, it can regenerate a fully functional limb over time, complete with bones, muscles, and nerves. This remarkable biological process is studied for insights into tissue regeneration and healing in other organisms, including humans.
If you mean as a starfish grows a new limb then no they don't
No , turtles can not regenerate a lost hand or limb .
Not in humans. Some animals and fish can regenerate their teeth.
no they can but humans can get sick with the poison
Yes. Salamanders are unique among the vertebrates as they can regenerate lost body parts. There are about 500 species of salamander.
no
Human limb regeneration is not fully possible at this point in time. The reason is that certain cells cannot be restored or "regenerated". For recovery of limb loss cells must be taken from another body that is alike to the one with limb loss. Stem cell research is the closest thing humans have gotten to regenerating and yet it is not funded but this is aside from the question. If a human were to regenerate a limb on its own it would require a extreme excitement of the cells healing the body and would dramatically shorten the life-span of the one recovering. The fact of the matter is, every injury and every moment we spend recovering from tissue damage leaves less cells to regenerate the body and provide a life-span and use of cells.
posibly, depending on the circumstances.
