SysoM1An Monstrosity: Dicephalus bicollis (GURLT). 
In some cases the head is only partially developed. 
The mouth or eyes may be entirely absent. Two 
heads may be present on one body, or two bodies 
only slightly connected to one another. In other 
cases, one body is present, apparently normal, with a 
small rudimentary fcetus attached to it,—a parasite.
