Caption: Polar bear underhair. Coloured scanning electron micrograph (SEM) of several shafts of hair from the underhair of a polar bear (Ursus maritimus). The fine underhair helps to provide insulation for a polar bear in the extreme cold of its Arctic habitat. These hairs are thinner than the coarse, hollow overhairs that also provide insulation (see Z927/132). Magnification: x420 when printed 10cm high.
