The undisputed darlings of Shetlands wildlife are the puffins, the most elusive is the sea otter. You have common and grey seals, whales in coastal waters, lots of seabirds and waders, Fair Isle is famous for migratory birds and Foula is the world capital of Great Skuas. Plenty of wildlife to choose from as a photographer. Not so wild but loveable are the Shetland Ponies and finally thousands of sheep, most of them are of the breed Shetland Sheep, are grazing in the hills and on the moorlands and if you are a fan of rare breeds you may look for the Foula Sheep an ancient breed, which lives, you probably guess, only on Foula (no other sheep is allowed on Foula to keep the breed pure).
Lots of critters to watch and to photograph!
