Cat hair, SEM
Cat hair, coloured scanning electron micrograph (SEM). The outside of the hair, the cuticle, is covered in overlapping scales of dead cells containing the protein keratin. Found exclusively in mammals, hair is one of their defining characteristics. This hair is from the British Blue (British Shorthair) breed of the domestic cat (Felis silvestris catus). The hair in cats serves as insulation and can be raised when threatened to give an appearance of increased size. Cat hair is a common cause of allergies in humans. Magnification: x265 when printed 10 centimetres wide

EDITORS COMMENTS
This print showcases the intricate details of cat hair, captured through a coloured scanning electron micrograph (SEM). The image reveals the outer layer of the hair, known as the cuticle, which is composed of overlapping scales made up of dead cells containing keratin protein. This particular strand belongs to the British Blue breed, also known as British Shorthair, belonging to Felis silvestris catus species. Hair plays a vital role in mammals and serves various purposes. In cats specifically, it acts as insulation and can be raised when they feel threatened, creating an illusion of increased size. However, it's important to note that cat hair can also trigger allergies in humans due to its common allergenic properties. With a magnification level of x265 when printed at 10 centimetres wide, this SEM image offers a closer look into the biological structure and complexity of feline fur. The false colouring applied enhances our understanding of multiple anatomical features such as shafts and scales. Nature enthusiasts and animal lovers will appreciate this photograph for its scientific value in zoology and biology studies. It highlights how even seemingly ordinary elements like cat hair possess remarkable beauty when examined under high-powered microscopes.
