The small, white, half-moon shapes found at the base of your fingernails are called lunula, which is Latin for little moon. Not everyone has visible lunula, and this is usually not a cause for concern. Sometimes, the lunula is hidden underneath the cuticle or skin at the base of the finger.

Fingernail moons are also called lunula, which is Latin for little moon
Fingernail moons are the rounded shadows at the base of your nails. They are also called lunula, which is Latin for little moon.
The place where each nail begins growing is known as the matrix. This is where the new cells are made that will make up the nail. The lunula is part of the matrix.
Not being able to see your fingernail moons doesn't always mean that something is wrong with your health. Sometimes, you may only be able to see lunula on your thumbs, or possibly not on any fingers at all. In these cases, the lunula is most likely hidden under your skin. Small or missing lunulae usually aren't a cause for concern. They're usually just hidden underneath the cuticle or skin at the base of the finger, especially on nail biters or those with more cuticle growth. On those who pick their cuticles, the lunula may be more prominent, as the cuticle has been compromised and more of the lunula and nail plate are on show.

Fingernail moons, also known as lunulae, are the rounded shadows at the base of your nails. The place where each nail begins growing is known as the matrix. This is where the new cells are made that will make up the nail. The lunula is part of the matrix.
The size and shape of your nail beds are largely determined by genetics, but there are other factors that can influence their appearance. For example, if you bite your nails, your lunula may be hidden underneath the cuticle or skin at the base of your finger. Similarly, if you pick your cuticles, your lunula may be more prominent as there is less cuticle to cover it.
In most cases, small or missing lunulae are not a cause for concern. However, if your lunula turns red, it may be a signal of heart failure, and if it turns brown, it could be a sign of chronic renal failure.
