The navel (clinically known as the umbilicus colloquially known as the belly button umbilical dip or tummy button) is a scar on the abdomen at the attachment site of the umbilical cord. All placental mammals have a navel and it is quite conspicuous in humans. Other animals’ navels tend to be smoother and flatter often nothing more than a thin line and are often obscured by fur.
