Pubic louse (Crab louse)

The coarse hair of the human body, most commonly in the pubic area; also found in eyelashes, eyebrows, beard, and chest hair.

Obligate ectoparasite; feeds exclusively on human blood by piercing the skin.

They are slow-moving and cling tightly to hair shafts with specialized crab-like claws. They cannot jump or fly and are usually transmitted through close physical contact or shared bedding.

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.
