Amazing and Unusual Body Features Found Only in a Few People

Some people are born with a tiny hole near the ear, a condition known as preauricular pit. It can appear on one or both ears, though it’s most often found on the right side. Thankfully, it’s usually harmless and rarely causes any health problems.

Fingers and Toes Without Nails

For illustrative purposes only
It may be hard to imagine life without fingernails or toenails, but for people with anonychia congenita, this is normal. This rare genetic condition results in missing nails at birth. It can affect all the nails or only a few. Despite its unusual appearance, it typically doesn’t impact a person’s health.

Constant Body Odor

For illustrative purposes only
Some individuals experience a persistent odor due to a condition called trimethylaminuria, with only about 100 documented cases. The body naturally produces a chemical called trimethylamine—known for its strong, fishy smell. Most people break it down through normal metabolism, but those with trimethylaminuria cannot, leading the odor to be released through sweat and breath.
People who are born with extra taste buds are referred to as supertasters. These individuals detect flavors—especially bitter ones—with far greater intensity than the average person. Foods like broccoli, chocolate, coffee, and grapefruit may taste surprisingly strong to them. Approximately 25% of the population are supertasters, and women are more likely than men to have this ability.

Unbreakable Bones
A tiny fraction of people possess extremely dense, exceptionally strong bones due to a genetic mutation known as LRP5. This condition drew attention in 1994 when a man survived a serious car accident without any fractures. Individuals with this mutation can withstand far greater force than the average person and even regenerate bone minerals more efficiently.

Seeing More Colors

For illustrative purposes only
Most humans see the world through three types of color receptors—red, green, and blue. However, people with tetrachromacy have a fourth receptor, allowing them to see millions of additional color variations that others cannot perceive. This rare trait is far more common in women, with up to 12% estimated to have the potential for tetrachromatic vision.
