Question: are nits the same as crabs?
Answer: They're a yellow-grey or dusky red colour and have 6 legs. Pubic lice are sometimes known as crabs because they have 2 large front legs that look like the claws of a crab. These are used to hold onto the base of hairs. The lice lay their eggs (nits) in sacs that are stuck firmly to hairs and are a pale brownish colour.
