Yakalo
Yaks can mate with American bison to produce yakalos as their offspring. The two species don’t interact with each other in the wild, and thus it’s clear that yakalos don’t occur naturally. In fact, the animals were produced by scientists in the 1920s as an experimental project regarding hybridization.

They were produced using pure bison or, for the most part, beefalos (which we learned about earlier). The heads of these animals look like those of bison while their body has a mix of bison and yak . Unfortunately, the experiments surrounding these hybrids weren’t successful and were abandoned.
