Beefalo
When explorers first introduced livestock to the New World in the 18th century, they inadvertently mixed bison and cattle. They were then crossbred more purposefully, but a few of them escaped. Wild herds of beefalo can now be found along the Grand Canyon. They cause mayhem by emptying watering holes and causing havoc wherever they go! It’s now up for discussion whether or not we can apprehend them.
Tigon
They crossed a male tiger and a female lion to create the Tigon. The parents’ sex is what distinguishes it from a Liger. You’d assume the tigon and the liger will be identical in appearance, but they’re not. Tigons do not evolve to the same size as ligers and do not experience dwarfism. They are, on average, younger than their immediate relatives.
