Penguin tongue. Coloured scanning electron micrograph (SM) of the tongue of an penguin,showing a dense arrangement of large,backwards-facing papillae on the dorsal (upper) surface. Papillae are projections on the tongue. Some house taste buds,but these papillae are purely mechanical,being thick and cornified to help the bird catch and hold on to fish. Penguins are aquatic,flightless birds that live in the southern hemisphere and feed on fish,squid and shrimps. Magnification: x5 when printed at 10 centimetres wide | |
