Icelandic horses (NOT ponies) - It is a major faux-pas to refer to Icelandic horses as "ponies" but it is OK to acknowledge that they are very cute.
Icelandic sheep - The inner fibres are fine, soft, and highly insulating. The outer fibres are long, glossy, and water-repellent. Icelandic literature claims that Icelandic sheep have been isolated from other breeds for over a thousand years and therefore they are one of the purest breeds in the western world.
