The webbing may consist of either a membrane or skin that differs according to the organism. Around the sixth week of fetal development, the body gives a signal through specific signaling proteins (one important one is called sonic hedgehog) to cause regression of these webs between the fingers and toes, and this process is termed interdigital apoptosis.
