Well, for the last image of January, image 031 is of a Common Frog. This was taken in my neighbours pond, where I have never seen so many frogs in such a small space! I used a variety of lenses, including the 100mm f/2.8 macro and the 17-40mm f/4.0 lens to get different perspectives of these amphibians. This one in particular was taken with the macro lens, as I wanted to get a lot fuller portrait of this individual. Frogs do not have external ears, but a circular depression (just smaller than the eye) behind the eye known as the tympanic membrane. The frog can hear when soundwaves strike this area. Male frogs have bigger tympanic membranes than the females.
Common Frog, Rana temporaria, West-Midlands, March, 2009.
