The wood louse (also known as sow bug), a crustacean, is so called because of its superficial resemblance to lice.
The crab louse is classified as Phthirus pubis, the body louse as Pediculus humanus humanus, the head louse as Pediculus humanus captitis, and the hog louse as Haematopinus suis.
The horse louse is classified as Haematopinus asini and the cattle lice as Haematopinus eurysternus and Linognathus vituli.

Two types of louse are adapted for living on man: the human louse, and the crab louse.
The human louse occurs in two forms, the body louse and the head louse, and these are very similar to one another.

These crustacean parasites are infamous for their aggressive attachment and feeding behavior, grasping tightly onto their hosts using small spines, hooked appendages, and a pair of large suckers.
A feeding louse will pierce and inject digestive enzymes into the skin or gills of a fish using a stylet -- a pointed, needlelike structure -- and then suck blood, mucus and enzyme-liquefied body fluids from the host.
Because of their rapid procreative turnaround, if left untreated, fish lice may quickly infest an aquarium, pond, or fishery and are therefore of major concern to the aquaculture industry.

Lice are spread from human to human most often by direct contact or contact with contaminated clothing, etc. Body lice are restricted most often to the human body and head (some authorities believe the head louse is a separate species).
Infestations with lice are not a serious problem (as long as the lice are not infected with a disease), but they can cause a number of uncomfortable symptoms, including skin irritations and intense itching.

Crab Louse, Pthirus pubis (Linnaeus) (Insecta: Phthiraptera (Anoplura): Pediculidae)
The crab louse occurs on man in many parts of the world and is almost exclusively a parasite of man. Ferris (1951) noted that it had been recorded from a chimpanzee from the French Congo.
Most of what is known of the biology of Pthirus is due to two authors (Nuttall, 1918, and Payot, 1920) who confined small numbers beneath a stocking or in a small enclosure on the skin and observed them daily.
