Sunda Pangolin (Manis javanica), a critically endangered species, has considerable variation in the reported periods of pregnancy, and more evidences are needed to verify their gestation duration. Fourteen cases of domesticated breeding were recorded in GFRI Pangolin Rescue and Breeding Base: nine births were given by female pangolins which might be fertilized before arriving at the base (Fig. 1 and 2), one cub was produced by a dam that might be pregnant pre-domesticated and died in the base (Table 3); one case unidentified in or out pregnancy; and three complete pregnancies recorded from mating to parturition within the base (Table 1), while two of them were second productions of the dams after arriving at the base. According to our preliminary results we suggested that M. javanica gestation period range from 5 to 6 months.
