Pubic Louse (Crab Louse)

Coarse hair on the human body, most commonly the pubic region, but also armpits, facial hair, or eyelashes.

Blood (obligate hematophagy); they feed exclusively on human blood several times a day.

They are slow-moving and use specialized claws to grasp thick hair shafts. They cannot jump or fly and require close physical contact (usually sexual) to transfer between hosts.

Risks include intense itching (pruritus) due to an allergic reaction to their saliva and potential secondary skin infections from scratching. They are not known to transmit diseases.
