Abstract
The article analyses sex- and age-related differences in tooth row length (TRL) in three shrew species – common shrew (Sorex araneus), pygmy shrew (S. minutes) and water shrew (Neomys fodiens). found in Lithuania, and the TRL correlation with body weight and length. No age- or sexrelated differences were found in TRL. Our sample did not reveal any TRL correlation with body weight or length. The TRL overlap in shrew weight groups was found to be very great. Thus, the TRL being a perfect trait for species identification is not suitable for body weight or length prediction.
