Humans With Tails
The human fetus has a tail during part of its development, however this has vanished by the time of birth. What looks like a tail may be caused by a number of different processes.
- It may be a true tail retain from earlier development. The human fetus has a tail early in development just after the 30th day post-conceprion, that it typically, but not always, lost before birth.
- it my be caused by a deformity of the spine
- it may be a growth such as a tumor. These defects sometimes appear higher up the spine such as on the back of the neck.

Oram, Chandre (India) [undated]
Chandre Oram works on a tea plantation. His tail is believed very lucky, except when it comes to finding a bride. His tail is a result of spina bifida, essential a split spine, and is reportedly 13 inches long (although I think he may be exaggerating there). Oram and others feeling his appearance is related to Hanuman, a god with a monkey-like appearance.
"True" / Vestigial Tail
A vestigial tail contained fat and tissue but no bone. It sometimes can be moved, and occurs more often in boys than girls. These are caused by the persistence of the tail that fetuses normally have, but that is generally reabsorbed by the time of birth,
A pseudo-tail may occur more to the side of the bpdy and is associated with spinal abnormalities.
- In 1977 a 10 year old boy complaining of pain while sitting was found to have a spine that terminated in an internal tail of 5 vertebrae, but that did not extend in the form of a visible tail.
