Hybrid animals have long captured the human imagination, appearing in mythology as " chimeras " and in modern digital art.
: A natural hybrid of a polar bear and a grizzly bear, often caused by changing migration patterns that lead to interbreeding.
: Some hybrids struggle to survive in the wild. For example, Grolar Bears may lack the specific physiology needed to thrive in either strictly terrestrial or aquatic environments, often finding themselves "too hot on land and too cold in the water".
: The most widespread hybrids, produced from a male donkey and female horse ( mule ) or a male horse and female donkey ( hinny ). They are prized for their strength and intelligence.
: An extremely rare hybrid of a bottlenose dolphin and a false killer whale.
