Normally in fiction users of regenerative healing factor have human or mostly human physiology. My question is whether a creature with a nonhuman body could have a regenerative healing factor. Could, for example, an ant, elephant, tiger, bear, beetle, shark, etc. have a healing factor? My specific creature I am looking to add a regenerative healing factor to is a creature with 40 heads, 40 legs, 20 arms, and 10 chests. This creature also has tons of tusks, claws, and horns. It also has 4 mouths and its heads are shaped like triangles of the irregular type. This creature has a wildly different physiology, but could it still be able to regenerate? There are other creatures that I want to give a healing factor to, but that would be too much for this post. The healing factor works by undoing injuries at 2/3 the speed they occur at. My explanation is that the users are possessed by an evil spirit. Evil spirits can possess any physical thing, such as a plant, animal or even a bar of soap.

In short, could a creature with a nonhuman physiology still have a healing factor/regeneration, and it still be internally consistent?
