| Pic: Monocephalus
thoracopagus |
There emerged news and circulating photo of a kid
(goat) born with eight (8) legs in Pathuon West Payam (Luonyaker) in Gogrial
East County of Warrap State this week.
The people in the area put the kid in “Ateny”
containing Dura and performed some traditional makings claiming that “it is a
miracle” as seen in the picture attached above.
As a veterinarian this is not something connected
with the traditional kind of thing or believes as people are circulating it
online.
It is a monster and the name of this particular
monster in the picture is called “Monocephalus
thoracopagus”.
It is a
posterior twinning type of monster
because the division of the body is at the lower (posterior) part of the body
(esp legs) while the thorax and the front (anterior) part of the body is single.
