In 1833, a letter from a Briton abroad was read before the Zoological Society of London. The contents of this rather unusual correspondence was later published in the society’s journal:
A note from Col. Hallam was read. . . . of two individuals of a race of pigs with only two legs, the hinder extremities being entirely wanting. The latter, Col. Hallam states, were observed ‘at a town on the coast in the Tanjore country [in India], in the year 1795: they were from a father and mother of similar make, and the pigs bred from them were the same.’
So, three successive generations of pigs missing hindlimbs. . . . essentially, pigs lacking hams.
The congenital absence of entire limbs is a relatively rare condition termed amelia. The lack of one or more limbs at birth is merely a symptom resulting from a variety of different causes, both internal and external. Developmental abnormalities can be genetic (internal) or they can arise from exposure to toxins, chemical substances, physical trauma, and radiation at crucial points during pregnancy (external). In addition, amelia can occur along with a suite of other deformities, especially in the face, or it can appear by itself in an otherwise healthy, normal individual.
It is these latter cases — adorable baby animals with missing limbs yet a plucky attitude — that have been enthusiastically picked up by news media. In 2010, an amelic piglet was born in Henan Province, China and named Zhu Jianqiang (“Strong-Willed Pig”), eventually reaching quasi-celebrity status worldwide. The pig’s owner, Wang Xihai, is quoted as saying: “My wife asked me to dump it but I refused as it’s a life. I thought I should give it a chance and unexpectedly it survived healthily (Daily Mail Reporter, 1 October 2010).” He even helped the pig learn how to walk balanced on its forelegs in a handstand, which it did with great success in about a month. At the time of the original news report, Zhu Jianqiang was still going strong and had obtained a healthy (albeit ham-less) weight of 110 pounds (50 kilograms).
The absence of hindlimbs has been popularly reported not only in pigs, but also in other domesticated animals. A Florida kitten named Anakin was found in 2012 without pelvis or hind legs and yet “. . . . he plays and scurries around by balancing on his forelegs, which he positions under his middle, and balancing with his tail (Hartwell).” An English Bulldog was born to a Arkansas breeder in 2015 with a truncated spine, no pelvis, and only vestigial hindlimbs. This pup, Bonsai, became a Facebook darling and a crowdfunding campaign raised over $24,000 to support medical expenses.
Like the pigs in Colonel Hallam’s 1833 report, existence without hindlimbs did not prevent these animals from living out their lives well into adulthood. At least in the case presented by Hallam, this included the somewhat mentally inconceivable act of breeding between two limb-less pigs. However, this carnival of cute oddities should not draw us into comfortable complacency. The congenital loss of limbs is the result of catastrophic disturbances in development. Many times, the results are fatal, if not outright cruel. For an amelic calf, veterinarians decided to euthanize the otherwise healthy animal because it could only drag itself around on its belly, causing raw skin abrasions. Bonsai the puppy was born with vestigial remnants of hindlimbs that had to be surgically removed. Also, Bonsai’s unsupported posture was putting pressure on internal organs — hardly good news for a bulldog, a breed already highly compromised with respiratory and other health problems. Needless to say, animals like Bonsai, Anakin, and Zhu Jianqiang will need extensive human care.
There is a sense of renewal at the delivery of a newborn. What we expect to find is something tiny, yet utterly new and perfect in every way. This is the body before the hard knocks of life, before battle wounds, poorly considered tattoos, run-ins with power tools. Congenital deformities can feel like a betrayal of these expectations. The birth of “monstrous” animals and babies were once seen as ominous signs that something was terribly amiss in the world. Such fearful portents may no longer signal religious heresies or political upheaval, but we must still think carefully about what they mean. We must be able to understand the difference between something so deep and hidden within our cells it is beyond our control, and warnings from an environment under siege. We must reconsider what is “normal”, what constitutes a meaningful life, and realize how our immediate culture defines those terms for us.
