Which animal has the thickest fur in the world?

The animal with the thickest fur in the world is the musk ox, also known as Ovibos moschatus. These large mammals are found in the Arctic regions of North America and Greenland. Musk oxen have a thick undercoat of wool-like fur called qiviut, which provides insulation against the cold Arctic weather. The qiviut is so warm that it can protect the musk ox from temperatures as low as -40 degrees Celsius.

Qiviut is one of the softest and warmest fibers in the world, and is highly valued for its properties. It is much finer and softer than sheep's wool, and does not contain lanolin, which can cause allergic reactions in some people. Qiviut is also very lightweight and breathable, making it an ideal material for clothing and accessories.

Due to the value of qiviut, musk oxen have been hunted for their fur in the past. However, today they are protected in most areas, and their fur is usually obtained through sustainable and ethical means. Qiviut is often used to create luxury items such as scarves, hats, and sweaters.
