Merino wool fibres, light micrograph. The fibres have overlapping scales, which is typical of animal hair. Merino wool is considered the best quality wool. It was originally taken from the merino sheep that is native to Spain. The world demand for the wool has led to the sheep's introduction to Australia and South America. Garments labelled "Pure New Wool" are 100% merino. Differential interface contrast. Magnification: x25 at 35mm size.
