Answer 1:
I do not know of any animal that can regenerate
the majority of its body. There are animals that
can regenerate their limbs such as salamanders and
there are animals that will regenerate their tails
such as in salamanders and lizards.
Sponges, which are very simple animals, will
re-aggregate if after you put them into a blender
and cut them up. This is a kind of a form of
regenerations but the cells are not re-growing,
they are just re-forming into a functioning
complete sponge.
