Horsies. There are tons of horsies.
They don't count them (?), but apparently there are about 100,000 horses in a country with around 300,000 people. The country hasn't allowed any other breeds in for over 1,000 years, so all of the horses are pure-bred Icelandic (although this really means VIking-age Norwegian, where they originally came from). I think they're mostly used to herd the sheep in the fall/spring, although back in the Viking days they were also good food and their bones were used to make tools.
