The probability of conjoined twins is also very low, the highest is 1 / 2800 in India, the lowest is 1 / 200000 in the United States. Conjoined babies are extremely rare in the world, but even there are conjoined bats with lower probability. It's just too creepy!
According to the daily mail of August 2, a conjoined two headed bat was found under a mango tree in southeastern Brazil in 2001. When it was found, its two ends are side by side, the trunk is connected as a whole, and there are still umbilical cord and placenta attached on the body, so it can be determined as a newborn. Ultrasound analysis showed that the bat had two hearts of similar size but separated from each other. Although it is not clear what causes identical twins to combine, this usually happens when the fertilized egg divides too late.
According to the researchers, most bats have only one cub in each nest, and normal bat twins are rare; moreover, bats are nocturnal animals, so the discovery is extremely valuable. Marcelo Rodrigues Nogueira, a postdoctoral researcher in biology at the State University of North Rio de Janeiro, told life science that he was' completely shocked 'when he saw conjoined bat twins. 'at work, I've been exposed to a lot of bats, some of which have impressive morphological features, but the conjoined twin bats are just amazing,' he said. '
It is understood that the incidence of conjoined twins in humans is also very low, the highest is 1 / 2800 in India, and the lowest is 1 / 200000 in the United States; however, the mortality rate can reach 80% within one day after birth. There are few conjoined twins in wild animals, only 19 cases occurred between 1671 and 2006. The conjoined bat is a large male bat of tropical fruit bat genus. The other two conjoined bats were found in 1969 and 2015 respectively.
