That is not pertinent to the original question, but to answer these questions,
First, fish self assemble through a process of cell division thus are the product of something smaller, a single fertilized egg.
Second, my parents willed me into existence by an act of fertilizing the egg. This is a method of procreation practised by many unrelated species, mainly because it yields variety and greater chance for survival.
The Silvery Salamander does not fertilize her eggs with male salamander sperm and her offspring are all female and identical clones of the mother, a bad survival strategy, resulting in the slow extinction of that particular "biotype" (a few dozen remaining specimen are now maintained in a few ponds as a severely endangered biotype).
