Sheep-goat hybrids, such as the toast of Botswana. Family Camelidae. Cama, a cross between a male dromedary and a female llama, also an intergeneric hybrid. Dromedary and Bactrian camels can crossbreed and produce a one large-humped Hybrid camel. Huarizo, a cross between a male llama and a female alpaca. Infraorder Cetacea. Family Balaenopteridae
Horns of a goat and a ram, goat's fur and ears, nose and canines of a pig, and mouth of a dog, a typical depiction of the devil in Christian art.

Cats [7] [71] and horses [7] [72] have been shown to hybridize with many closely related species. The archaeological and genetic data suggests that long-term bidirectional gene flow between wild and domestic stocks – including canids, donkeys, horses, New and Old World camelids, goats, sheep, and pigs – was common.
The goat problems do not yield any new mathematical insights; rather they are primarily exercises in how to artfully deconstruct problems in order to facilitate solution. Three-dimensional analogues and planar boundary/area problems on other shapes, including the obvious rectangular barn and/or field, have been proposed and solved. [1]
Goats like to climb things, and horses don’t mind carrying things on their backs. It’s a fundamental trait of each species, so if you put them in an enclosure together, it’s bound to happen ...
