Walrus. Thermogram of a walrus (Odobenus rosmarus). A thermogram shows variation in temperature on the surface of an object,measured by the long-wave infrared radiation it emits. The temperature scale is colour-coded and runs from purple (0.1 degrees Celsius,coldest) through indigo,blue,green and yellow to red (warmest,32 degrees Celsius). This image illustrates how the blubber covering most of the head of a walrus insulates it from the cold. Where the blubber is absent,(the eyes and the nostrils),heat loss is greatest | |
