THE “ADHESIVE” HAIRS ON A GECKO’S TOE
Nature News & Comment
This microscopic image shows the forest-like arrangement of hairs on a gecko’s toe that gives the animal its gravity-defying ability to scurry across ceilings.
Each foot has hundreds of thousands of these hairs, called setae, which fray into smaller hairs with split ends called spatulae. The hairs’ strong grip has inspired the design of medical adhesives.
This image was taken by Dennis Kunkel, a photomicrographer in Hawaii. It is part of Life: Magnified, an exhibition of scientific images on display at Washington Dulles International Airport’s Gateway Gallery from June to November.
