I seen this in Oprah, nanghihina ako when i saw it...

if you believe in science, we all started microscopic liquid, but some abnormal chemical combinations or for whatever reasons, some can start developing strange..


we really have not seen any of this babies for thousands of years, becuase they can't survive, but with the technology that we have today, it is possible to save these babies ..

parasitic twin


Wikipedia
parasitic twin
A parasitic twin is the result of a situation related to the process that results in teratomas, vanishing twin, and conjoined twins – two unique embryos begin developing in utero, but something goes wrong. Parasitic twins are also known as asymmetrical conjoined twins or unequal conjoined twins. Parasitic twins are a variation on conjoined twins—except one of the twins stopped developing during gestation and is now vestigial to a healthy, otherwise mostly fully-formed individual twin. They are defined as parasitic, rather than conjoined, by being incompletely formed or wholly dependent on the body functions of the complete fetus.

Conjoined-parasitic twins united at the head are described as craniopagus or cephalopagus. Craniopagus occipitalis is the term for fusion in the occipital region; craniopagus parietalis is when the fusion is in the parietal region; craniopagus parasiticus is term for a parasitic head attached to the head of a more fully-developed fetus or infant.


Specific types of parasitic twin

Fetus in fetu
Fetus in fetu describes an extremely rare abnormality that involves a fetus getting trapped inside of its twin. It continues to survive as a parasite even past birth until it grows so large that it starts to harm the host, at which point doctors usually intervene. Invariably the parasitic fetus is anencephalic (without a brain) and lacks internal organs, and as such is unable to survive on its own.


Acardiac twin
An acardiac twin is a parasitic twin that fails to develop a head, arms and a heart. The resulting torso can leech blood flow from the surviving normal twin, causing extreme stress on the normal fetus's heart.

Prenatal surgery must be performed if the normal fetus is to survive.

Baby stable after second head removed
10-month-old girl suffered from 'parasitic' twin birth defect

http://www.msnbc.msn.com/id/6998205?GT1=6190

noon nakikita lang natin sa mga komiks, yung mga weird na ganito , but now with the internet, we know they exist and ever existed even long time ago...
kaya noon if they live with their other half, they keep it , dahil walang pang tayong magaling na technology to make sure it will survive.. wala pang experts noon how to do it right...lalo na yung 2 ulo, kaya nanganganib din yung host, noon they don't surive that long..
http://altsexcolumn.com/mt/archives/2004_10.html

do u remember , yung sa komiks noong araw, kasi noong marami kaming boarders galing sa bisaya, kung mag-aabroad doon sila tumitira sa akin, para matuto sila ng tagalog, bumibili sila ng mga komiks, dahil natural daily conversation ang gamit na tagalog, dahil yung mga ibang bisaya lumaki, ang tagalog nila, eh napakalalim daw.. he heh e!!1

then hindi ko makalimutan yung story sa komiks noon, iangg batang laging pinagtatawanan ,pero masipag, ang tawag kuba.... then yung nag-asawa na pala siyaeh...hindi naman pala kuba, lagi lang nakatago yung extra pa niyang ulo sa likod... totoo pala ang ganito...

yung mga i-nopera para pulutin kung dalawa ang ulo, marami ang hindi successful, at namamatay, but now, we heard na marami din naman successful at nabubuhay ang bata, tulad ng muslim na nanay diyan sa pintures..
