A mutant pig, born with two heads and eight legs, died just minutes after birth on a farm in China. A Chinese farmer, Gao Baiqi, who raises animals, said he "had never seen anything like it."

The mutant piglet appeared to have been born with a parasitic twin, according to Daily Mail Monday. Baiqi, who lives in Fe County in Linyi City, located in China’s eastern Shandong Province, said he discovered the mutant piglet among the litter after birth.

"Besides having one head, two bodies and eight legs, the piglet appeared normal and had all other organs," Baiqi told Asia Wire.

Because it was weak, Baiqi reportedly planned to nurture the abnormal piglet by hand instead of letting it feed from its mother. It was born with underdeveloped skin, and it jerked and thrashed about before it abruptly stopped breathing.

"I had prepared milk and wanted to feed it myself, but it died in a few minutes," Baiqi said. He reportedly buried the piglet before he showed it to nearby residents.

Baiqi hasn’t figured out what caused the piglet’s deformities. However, the birth defect was possibly the result of an egg that hadn’t separated during conception, as is the case in human conjoined twins.

According to a report by Berkeley regarding evolution and causes of mutation, deformities happen for many reasons and are "naturally occurring."

"For example, when a cell divides, it makes a copy of its DNA — and sometimes the copy is not quite perfect. That small difference from the original DNA sequence is a mutation," the report read.

External influences also caused mutations, according to the report.

"Mutations can also be caused by exposure to specific chemicals or radiation," the report continued. "These agents cause the DNA to break down. When the cell repairs the DNA, it might not do a perfect job of the repair. So the cell would end up with DNA slightly different than the original DNA and hence, a mutation."

Another deformed pig surfaced in China in 2015, though this time the animal bared what some said resembled a penis on its forehead, according to Mirror. A Chinese farmer named Tao Lu noticed the deformed pig among the litter after birth.

"It was a large litter, and the mutant was one of the last of 19 piglets to be born," Tao said. "All the others were normal, just this one was really bizarre.

"It is a shame it died, I could have got more money for it than for the rest of the family put together based on what people were offering me on the phone," he continued.

The farmer said he intended to put the malformed pig on display for locals to behold. One local, Wu Kung, 32, witnessed the animal close up.

"I was one of a dozen people who went there to see the piglet, and it really did have human face and exactly like he said, a penis growing out of its forehead," he said.
