Embryonic Stages Stage 5Both front and hind limb buds wider than they are long. Hindlimb buds are slightly bigger than forelimb. Stage 6Hindlimb more distinct than forelimb. Distal limb buds are paddle shaped. Stage 7Paddles wider than in previous stage. Medial digit condensation beginning to be visible. Stage 8Condensation of digit cartilages are visible with slight thinning of internal webbing but no regression. Stage 9Distal tips of digits freed of internal webbing. 4th digit noticeably larger. Stage 10Digital webbing receeded to half its length on digits. Slightly elongated medial digits. Stage 11Digital webbing has fully regressed. Pinching at distal tips eventually will form claws. Stage 12Further pinching at distal tips. Stage 13Pinching at distal tips has formed into claws. Stage 14 Stage 15 Stage 16 Stage 17
