The absence of sexual dimorphism in Pyrenean desman Galemys pyrenaicus (E. Geoffroy, 1811) makes it difficult to sex live animals. This paper presents a method of sexing desmans observing their external genitals. Based in a sampling of 49 animals from the north of Spain, it was possible to identify the penis of males, independently of the age or season.

This paper provides a criterion to determine the age of live Pyrenean desmans Galemys pyrenaicus (E. Geoffroy, 1811) by observing dental wear. The criterion is based on the comparison of the estimated age by examining the growth rings on dental sections and the wear observed on the upper canine tooth. Bone matter from different areas in the north of Spain was studied. This species has a high life expectancy. In its natural environment, the desman may live to be over 5 years old.
