The first deer Lowly Darton posted is a muntjac, and can be hunted in the UK, it was transplanted there last century. The second deer is a Chinese Water deer, and can also be hunted in the UK, in much smaller numbers. Both come from Asia. The musk deer is severely endangered, and I don' t know of anywhere they can be legally hunted. They' re farmed in China for their musk, used in traditional medicine. That' s why they are being pushed to extinction in the wild.
They look similar to the Chinese Water deer.
