Mammal Crosses:
* Zonkey: A cross between a zebra and a donkey.
* Beefalo: A cross between a domestic cow and a bison.
* Dzo: A cross between a yak and a cow.
* Cama: A cross between a llama and a camel.
* Grolar Bear: A cross between a polar bear and a grizzly bear.
* Narluga: A cross between a narwhal and a beluga whale.
Bird Crosses:
* Mule Duck: A cross between a mallard and a Pekin duck.
* Golden Pheasant: A cross between a golden pheasant and a ring-necked pheasant.

Other Crosses:
* Wholphin: A cross between a bottlenose dolphin and a false killer whale.
* Coywolf: A cross between a coyote and a gray wolf.
* Savannah Cat: A cross between a domestic cat and a serval.
* Bengal Cat: A cross between a domestic cat and an Asian leopard cat.
Important Note: Many of these crosses are created for specific reasons, like increased meat production in beefalo or the desired characteristics of a savannah cat. However, some crosses occur naturally in the wild, like the narluga and coywolf.
It's also worth noting that many animal crosses are not as successful as others. Some offspring are infertile, and others may have health issues. This is because different species have different numbers of chromosomes, and these can sometimes clash during the development of the offspring.
