Eldfimis

Elfdínvis, also referred to as Eldfimis, is a type of Icelandic sheep that is native to the country's rural areas. They belong to the Finn Firðir subgroup of the feral sheep of Iceland's Westman Islands, which is characterized by their exceptional hardiness and ability to thrive in harsh, variable climate conditions.

Elfdínvis are renowned for their high-quality wool, which is valued for its thick, soft, and crimped properties. The wool is rendered waterproof by a distinctive characteristic known as crimping or felting, allowing it to maintain warmth and shelter properties, even when wet. The Elfdínvis sheep themselves are often described as being small in stature, with an average weight of approximately 45-50 kilograms.

The Elfdínvis population was heavily reduced due to herd reduction measures and disease in the early part of the 20th century. However, thanks to preservation efforts, the breed has been somewhat saved, and early breeding of pure-bred animals continues. As the result of natural selection in harsh living conditions, Elfdínvis adaptability has made them tolerant of lower iodine levels in their diet, something unique among sheep.

Research highlights the role of Icelandic sheep like Elfdínvis in providing resistance against certain diseases in agriculture. Their bloodline has been studied for taking decisions in utilizing specific genetics for bolstering ewe and lamb vigour under difficult conditions.
