Image of human body louse
Description:
Under a relatively low magnification of 97x, this 2006 scanning electron micrograph (SEM) depicted a dorsal view of a male body louse, Pediculus humanus var. corporis. Occupying the field of view, was the insects left leg of its first pair of legs. There was a piece of debris attached to the distal claw tip of this appendage. The jointed nature of its extremities, designates this organism as a member of the phylum Arthropoda, and the fact that there are three pairs of legs, the louse is, thereby, placed into the class, Insecta. Note the small, hair-like structures adorning the exoskeletal surface of this insect. These are known as setae, and are not hairs at all, but extensions of the chitinous exoskeletal surface, which provide the organism with sensorial data about its surroundings.
