Pubic louse (Crab louse)

Primarily found in the pubic hair of humans; can also occur in other coarse body hair like chest hair, eyebrows, or eyelashes.

Obligate ectoparasite; feeds exclusively on human blood several times a day.

Unlike head lice, they are slow-moving and adapted for grasping coarse hair with large, crab-like claws. They are usually transmitted through close physical contact.

Risks include intense itching (pruritus) due to an allergic reaction to their saliva, and skin discoloration. They are not known to transmit infectious diseases, but infestation indicates a need for medical treatment.
