Pubic lice are little insects that attach themselves to pubic hair. Their nickname is crabs, because they have front legs that look like the pincher claws of a crab.
They are transmitted by sexual contact and therefore considered a STD. But it can also be contracted through physical contact with bed linens or a shared towel, although this is exceptional since they need the human body to survive.
They can occur on all places covered by hair, except for the head. But they are generally found in the genital area.
The most obvious symptom is itching, which is normally worse at night.
The lice are oval and usually yellow to white. Because they are very small they may be hard to spot. Sometimes you can see the nits (lice eggs) that are attached to the hair shaft close to the skin.
