Polycephaly is a condition of having more than one head.

A variation is an animal born with two faces on a single head, a condition known as diprosopus.

Dicephalic conjoined twins (dicephalus dipus):
In 1990, Abigail and Brittany Hensel were born in Minnesota, United States[11]
In 2000, Ayse and Sema were born in Kahramanmaraş, Turkey[16]
In 2003, June 13, twin girls named Huda, and Manal Abdel Nasser Mohammed Mahmoud, were delivered Caesarean section in a hospital in Asyut, Egypt[17]
In 2003, Sohna and Mohna were born in India[18]
In 2006, Syafitri was born in Indonesia[13]
In 2007, Mary Grace and Mary Divine Asis were born in the Philippines having only one heart. [19]
In 2008, August 25, a baby boy named Kiron was born with two heads in south-western Bangladesh. [20] Kiron had been born from one embryo but a serious development anomaly had been present resulting in the double heads. The baby was described by the gynaecologist present at the birth as having "one stomach and he is eating normally with his two mouths. He has one genital organ and a full set of limbs". [20] However the clinic initially had been unable to determine whether he had one or two sets of vital organs. [20] The mother and baby had been taken to a hospital in Jessore, but the hospital staff had attempted to refer him to a more resourceful hospital in Dhaka in an attempt to save it. However the family lacked the money to take him there despite donations. [21] Although the baby had initially been healthy and was eating well, on August 26 the baby encountered breathing difficulties and a fever and subsequently died two days later on August 28.[21]
Craniopagus parasiticus - parasitic twin head with an undeveloped (or underdeveloped) body attached to the head of a developed twin:
In 2003, Rebeca Martinez was born in the Dominican Republic with an extra head but died 7 hours after surgery at the age of 8 weeks.[22]
In 2004, Egyptian Naglaa Mohamed gave birth to Manar Maged who had the head and undeveloped torso of another child attached. In 2005, the second head was removed, and later that year Naglaa appeared on the Oprah Winfrey show with her surviving child.[23] Manar died from a brain infection in 2006.[24]
Unconfirmed reports
Maria and Consolata Mwakikoti from Tanzania (b. 1999)
Luz and Milagros Romero-Saucedo of Argentina (b. 1999) may or may not be of the dicephalus type.
Carmen and Lupita Andrade-Solis (b. 2000), originally from Mexico, currently resident in Connecticut, United States
In 2008, a female child named Lali was born to Vinod and Sushma Singh of the Gautam Buddha Nagar district of Uttar Pradesh in India. [25] The family has refused special medical care, and recent reports state that the case is not one of polycephaly, but a condition called craniofacial duplication, a rare congenital disorder. [26]
Non-human animals
Cats
Two-faced kitten, Lausanne
There have been numerous reports of two-faced cats; most die soon after birth. Reports of two-headed kittens are common, relative to other animals, because of their status as household pets. Recent two-headed kittens include:

Specification of the anterior dorsal/neural axis in vertebrates is now very well understood. There are lots of famous experiments in developmental biology that result in embryos with multiple heads. One of the genes that has been identified as playing an important role in this process is aptly named Cerberus (after the mythological three-headed-dog). Mis-expression of this gene during embryonic development causes the development of extra heads.
The brain/neural net plasticity is incredible for adaption.
Good on them
It's almost beyond imagining.
