    Human tails[edit]

    human embryos have a tail that measures about one sixth of the size of the embryo itself.[1] As the embryo develops into a fetus, the tail is absorbed by the growing body. The developmental tail is thus a human vestigial structure.[2][3] Infrequently, a child is born with a "soft tail", which contains no vertebrae, but only blood vessels, muscles, and nerves, although there have been several documented cases of tails containing cartilage or up to five vertebrae.[4]
    Humans have a "tail bone" (the coccyx) attached to the pelvis, formed of fused vertebrae, usually four, at the bottom of the vertebral column. It does not protrude externally.
