The tiger muskellunge, or tiger muskie, is the first hybrid animal on this list that has not been created as the result of humans and naturally occurs in the wild. This carnivorous fish is a cross between the northern pike and the muskellunge, which both reside in freshwater lakes and rivers in upper North America.
Tiger muskies are born sterile, but like most other hybrid animals, they grow very quickly and are less susceptible to disease. In one study, tiger muskies grew 1.5 times faster than non-hybrid muskellunge.
Among anglers, they are called the “fish of 10,000 casts” because they are so difficult to catch.
