Yes, in a rare phenomenon called Vanishing Twin Syndrome, one twin can be absorbed by the other (or the mother/placenta) in the womb, essentially being "eaten" or reabsorbed as the surviving twin develops, though it's a biological process of tissue absorption, not active cannibalism. This usually happens early in pregnancy when one fetus stops developing, and its cells are taken up by the stronger twin, sometimes leading to the survivor becoming a chimera (having two sets of DNA).
Yes, they can absorb their twin, more or less completely (if not completely, some twin's body parts become their own, which is called chimerism). It's called vanishing twin syndrome.
When one twin dies or one or two of a set of triplets dies during the first 12 weeks of a pregnancy it doesn't usually affect the development of the remaining twin or triplet(s). In a twin pregnancy this is known as 'vanishing twin syndrome'.
Sometimes some evidence remains. Before ultrasounds, doctors found proof of vanishing twins by examining the placenta after the birth of the surviving twin. Today, doctors diagnose vanishing twin syndrome by using ultrasounds. An early ultrasound may show two babies, and a later ultrasound may show only one.
In parasitic twins, one ceases development during gestation and is vestigial to a mostly fully formed, otherwise healthy individual twin. The undeveloped twin is termed as parasitic, because it is incompletely formed or wholly dependent on the body functions of the complete fetus.
Most babies with craniopagus parasiticus are stillbirths but three documented cases survived birth with the help of modern medicine [5, 6]. We report the case of a baby girl delivered alive with a parasitic co-twin and a successful separation performed 1 week later.
More bluntly, yes, you would be having sex with a shared sexual organ, which usually means that both will experience the same orgasm at the same time.
The results suggest that twin fetuses are aware of their counterparts in the womb, that they prefer to interact with them, and that they respond to them in special ways.
Like in all other types of miscarriage, the vanishing twin sadly cannot reappear. Vanishing twin syndrome is diagnosed more frequently these days than in decades past due to the use of ultrasound in early pregnancy: It's said to affect up to 30 percent of twin or multiple pregnancies, according to Kalish.
Studies have shown that cfDNA from the vanishing twin can still be present in the maternal plasma up to at least 8 weeks post fetal demise [14], and possibly as long as 15 weeks [16].
A selective termination of the acardiac twin reduces the risk of death of the pump twin. Selective reduction is used when a mother is carrying an unsafe or undesirable number of fetuses in a multiple pregnancy, which are common in medically assisted pregnancies.
What happens next? After a fetus dies, labour will usually begin on its own within 2 weeks. But if you don't want to wait that long, you can choose to have labour induced.

A daisy baby is another name for babies with TTTS. The Twin-to-Twin Transfusion Syndrome Foundation coined the term after its founder planted daisy seeds with her surviving twin son in their backyard. The daisy field is a symbol of hope that all babies affected by TTTS will survive.
Heteropaternal superfecundation is an extremely rare phenomenon that occurs when a second ova released during the same menstrual cycle is additionally fertilized by the sperm cells of a different man in separate sexual intercourse taking place within a short period of time from the first one 1-4.
Fetus in fetu (or foetus in foetu) is a rare developmental abnormality in which a mass of tissue resembling a fetus forms inside the body of its twin. An early example of the phenomenon was described in 1808 by George William Young. Anteroposterior abdominal radiograph shows a soft-tissue mass in the right hemiabdomen.
Age: If you're over the age of 35, you're more likely to release multiple eggs during ovulation. Family history: If your mother's side has a history of fraternal twins, there is a chance you could conceive twins naturally.
If this event happens in the first trimester of the pregnancy, the surviving twin will most likely develop without further consequences. However, if the fetal death occurs after mid gestation (17 weeks' gestation) there is an associated increased risk of preterm labor, IUGR, preeclampsia, and perinatal mortality [5,8].
In about 2/3 of the MZT cases, the splitting occurs 4-8 days after fertilization, and the placenta will be monochorionic-diamniotic (i.e one placenta and two amniotic sacs).
Superfetation is the concept of getting pregnant while you're already pregnant. It's incredibly rare—but entirely possible. Research says that there have only been 14 documented cases of superfetation. However, experts say it's becoming slightly more common due to the use of assisted reproductive technology.
In some instances, the dead twin is compressed into a flattened, parchment-like state known as fetus papyraceus. Vanishing twins occur in up to one of every eight multifetus pregnancies and may not even be known in most cases.
Although both survived the surgery, believed to be only the second of its kind, they had varying degrees of impairment, with Ganga having brain damage and Jamuna being unable to walk. Ganga subsequently died in 2008 of pneumonia and meningitis. In 2016, a book was published in Singapore about their lives.
The data affirm more limited observations of conjoined twins. Substantial inde- pendence of sleep and waking was present. One-fourth of the waking time of one twin and one-third of the waking time of the other occurred in the presence of sleep of his twin.
