We report data on the somatometry of the white-toothed shrew Crocidura russula (Hermann, 1780), based on 302 specimens (153 males, 149 females) captured between 1980 and 1982 in the Ebro Delta (northeastern Spain). Variations in body size and weight were analysed according to sex, relative age (estimated by tooth wear) and month of capture. Relative and seasonal growth were also studied. No statistical difference in body size was detected between sexes. The specimens showed highest growth rate up to about fourteen weeks of age. Afterwards, most of the variations detected in body length and especially in weight were basically related to sexual stage. Specimens born in the first litters of the year grew faster than those born at the end.
