Nomenclature

The naming of hybrid animals depends on the sex and species of the parents. The father giving the first half of his species' name and the mother the second half of hers. (e.g. a pizzly bear has a polar bear father and grizzly bear mother whereas a grolar bear's parents would be reversed.)
