Some humans are born with tails although being born with a tail or tails is rare in humans.

The race that is born with tails are Caucasians as 50 percent of Caucasians are or were born with a tail.

The longest human tail is 33 cm or 1 ft and 1 inches in length which is on a human and Indian plantation worker named Chandre Oram.

A vestigial tail can be removed through surgery as the true vestigial tail is made up of adipose and muscular tissue which means these vestigial tails can be removed with a simple excision.

Some people with vestigial tails can move them although not everyone can.

The vestigial tail does contain nerves, blood, adipose tissue, connective tissue and muscles although they lack bones.

A vestigial tail is very rare and there are only 40 cases of human tails being reported.

A vestigial tail in humans is called the tailbone or also the coccyx which is located at the end of the spine below the sacrum.

Most humans born grow tails in the fetal stage in the womb but them embryonic tail goes away by 8 weeks and most often becomes the tailbone or coccyx.

Vestigial means a body part or organ that is remaining in a form which is small or imperfectly developed and so it's not able to function.

Also being or having the form of a vestige.

A pseudo tail also known as Pseudotails are varied lesions that have in common a lumbosacral protrusion and a superficial resemblance to persistent vestigial tails.

The most frequent cause of a pseudotail in a series of ten cases obtained from the literature was an anomalous prolongation of the coccygeal vertebrae.

True tails contain muscle, adipose tissue, and connective tissue whereas pseudotails contain bone, cartilage, and remnants of notochord.

A “vestigial tail” describes a remnant of a structure found in embryonic life or in ancestral forms.

During the 5th to 6th week of intrauterine life, the human embryo has a tail with 10–12 vertebrae.

By 8 weeks, the human tail disappears.

There are several human atavisms that reflect our common genetic heritage with other mammals.

One of the most striking is the existence of the rare 'true human tail'.

It is a rare event with fewer than 40 cases reported in the literature.
