While hybrids like ligers and zorses are well-known, they do not naturally occur in the wild and are products of captivity. However, some hybrid animals do arise naturally, such as the coywolf—a cross between coyotes and wolves—which combines the size and pack-hunting skills of wolves with the adaptability of coyotes, allowing them to thrive in urban areas. Another example is the narluga, a rare hybrid between narwhals and beluga whales, evidenced by a unique skull found in Greenland and observations of interspecies social behavior. Additionally, grolar bears, hybrids of polar and grizzly bears, have emerged in the wild due to overlapping habitats caused by climate change, with some scientists hopeful these hybrids may aid polar bear survival.

In captivity, hybrids like ligers (lion-tiger crosses) and zorses (zebra-horse crosses) exist but are unlikely to occur naturally due to differing habitats and behaviors. These captive hybrids often raise ethical and health concerns. Similarly, hinnies and mules are hybrids of horses and donkeys, resulting from specific parental pairings, and are well-known examples of crossbreeding between closely related species.
