IMPORTANT: An absent lunula is perfectly natural on the little finger!

Many people have 8 lunula, though some of them might be hidden under the cutticles - because the lunula are typically diminishing in size from the thumb to the little finger. Fewer than 8 lunula can signal various vulnerabilities such as: malnutrition, protein deficiency, vitamin A deficiency, anemia (deficiency of red blood cells), not enough oxygenation, poor circulation, numbness, or heart disease [source: Medscape]

No lunula at all on all fingers (missing lunula) has been recognized as a feature of various chromosome abnormalities.
