    When there is a case of fetus in fetu the "twin" is alive in the sense that an organ is alive, but how does it live inside the host twin? Does it grow and move like a fetus does or is it just purely cells in the shape of a human? And in the case of the man in India with the twin in his belly, how did the twin gross hair and nails inside him and what happened to the "twin" once it is removed?
    Thank you!

    Typically the growth feeds by a sort of shortcut umbilical cord that, rather than bypassing the host to a mom-fed placenta, takes at least most of its blood from the host. In this way it may live after birth so long as the host lives.

    In contrast twins, including conjoined twins, have separate umbilical cords.
