A parasitic twin is a rare medical condition in which one twin is born physically attached to the other, but is not fully formed and relies on the latter for survival. This condition is also known as asymmetrical, absorbed, or conjoined twin. Another term used for this condition is the "parapagus twin." A parasitic twin can also be referred to as the undeveloped, adjoined, or sibling twin. In medical terms, it is called "autosite" or "autosite conjoined twin."

Although parasitic twins are rare, they are a fascinating subject of study for medical professionals, scientists, and people worldwide.
