A total of 1207 specimens (717 females and 490 males) of the Blackmouth catshark Galeus melastomus (Chondrichthyes: Carcharhiniformes) were collected in Sardinian waters at depths from 120 and 1600 m. A detailed macroscopic and histological description of the maturity stages was reported fir both sexes. Mature individuals were found during the entire year suggesting continuous mating and spawning. Females matured at higher size than males and both sexes showed a late maturity (females L50=45 cm TL; males L50=42.4 cm TL).
