The early development and adult size of Natalobatrachus bonebergi were investigated. Newly hatched tadpoles were normally about 12,5 mm long. Fore-limb emergence occurred at a total length of 35 to 41 mm after 60 to 125 days of development in the laboratory. Body length was 12 to 13 mm at the end of metamorphosis, and reached two to three times this length at sexual maturity. Hind-limb growth corresponded closely in natural and laboratory populations and served to indicate pre- and pro-metamorphic phases. Rapid increase in hind-limb length occurred only after tadpoles had reached 30 mm in total length.
