Identifying distinct individuals is essential to increase the accuracy and completeness of population counts. We are interested in the black and yellow dorsal pattern on the back of the individuals and in the tail pattern of larvae as these are unique to each individual. Full body pictures will help us more easily to identify the individual. As fire salamanders are mainly nocturnal, good light conditions are also helpful. If you have more than one picture, no problem at all; this might even help us to identify the individual more easily. Although we prefer full body pictures from above of the individual, pictures from the side might help us to identify the sex of the individual.
