Glassy Radiolarian Beauty The shells of radiolarians rank among some of the treasures of the ocean, with their intricate, gorgeous geometry. The shells are made of silica, which protects the single-celled animals as they drift as zooplankton in the ocean. This image, taken at 120x zoom, was an honorable mention in the 2012 Nikon Small World photomicrography competition.

Intestinal villi. Coloured scanning electron micrograph (SEM) of villi on the lining of the small intestine. Villi are finger-like projections that line the surface of the small intestine and increase the surface area available for the absorption of nutrients from digested food. Magnification: x135 when printed 10 centimetres wide.
