Polar bear underhair, SEM
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

EDITORS COMMENTS
This print showcases the intricate beauty of a polar bear's underhair, captured through a coloured scanning electron micrograph (SEM). The image reveals several shafts of hair from the underhair of a majestic polar bear, known scientifically as Ursus maritimus. The fine underhair plays a crucial role in providing insulation for these incredible creatures living in the extreme cold of their Arctic habitat. These hairs are thinner compared to the coarse, hollow overhairs that also contribute to insulation. Through this magnified view at x420 when printed 10cm high, we can appreciate nature's remarkable adaptation to thermal regulation. Each strand acts as an insulating barrier against the frigid air surrounding them, allowing these bears to thrive in one of Earth's harshest environments. This photograph not only highlights the zoological marvels found within wildlife but also serves as a reminder of our planet's delicate balance and its ability to nurture life even in seemingly inhospitable conditions. It invites us into the world of polar bears and encourages us to appreciate their resilience and beauty. With every glance at this mesmerizing image, we gain insight into the wonders hidden beneath fur and skin while fostering admiration for these magnificent creatures that call our Arctic regions home.
