The elephant louse is not in danger of extinction. They are very tiny and are capable of reproducing in large numbers over and over (Klots and Klots 1979). The only threat to the elephant louse comes to the decreasing population of elephants throughout the world.

Haematomyzus elephantis does not posses any threat to humans (Klots and Klots 1979). They do not infest man and are not involved in human disease transmission. These lice are ectoparasitic and can only live on elephants (Grzimek 1972). However, the elephant louse does have a veterinary importance in zoos in particular (Grzimek 1972). Massive infestations of the elephant louse in elephants at zoos can be fatal to the offspring of elephants. Infections can cause a massive drop-off of the female elephant eggs released in the ovaries (Grzimek 1972). The elephant population can decline from an onslaught of the Elephant Louse.
Haematomyzus elephantis acts more like a scavenger than a parasite (Grzimek 1972). It does not take in food by sucking. It possesses incredibly strong biting mandibles on the rostrum located on the head (Klots and Klots 1979). The louse uses these mandibles to bite through the tough skin of elephants. This louse is not known to drink the blood of elephants, as was long thought, but instead eats off the hairs and miscellaneous debris on the elephant.(Klots and Klots 1979).
Haematomyzus elephantis commonly known as the elephant louse, lives and feeds on the skin of elephants (Arnest 1985). Areas such as in the African plains where herds of elephants roam are suitable environments for these lice to dwell. The elephant louse follows the elephants whenever they move. They are transmitted from one elephant to another when two elephants come in contact with each other. Zoos are also areas where this louse is found (O'Toole 1986). The number of lice present in zoos is low however, due to the veterinary care given to elephants (O'Toole 1986).
Biogeographic Regions: oriental (Native ); ethiopian (Native )
The elephant louse thrives in habitats suitable for elephants to survive. These are the warm climates of India and the African grasslands (O'Toole 1986). The louse has adapted itself to survive the extremes that elephants endure in this part of the world. This is because the elephant louse can only survive on elephants. The tough, flexible skin also permits the louse to survive in the climate (Grzimek 1972).
Terrestrial Biomes: savanna or grassland ; scrub forest
Haematomyzus elephantis is oval or elongated and ranges between 0.5 to 6 mm in length. The body and head are dorso-ventrally flattened with the head being larger than the thorax (Grzimek 1972). The skin of the louse is tough and flexible with the coloration being pale to tan with some having yellowish markings or dark brown or black bands on their body (Grzimek 1972). The head has very small eyes; in some the eyes are absent. They also have short antennae on the head (Klots and Klots 1979). The front of the head is prolonged into a rigid snout, called the rostrum, with biting parts on the tip (Klots and Klots 1979 ). These lice never had wings. They have reduced legs with large adhesive pads for better traction on the legs. Cerci are also absent on this louse (Grzimek 1972).
Other Physical Features: ectothermic ; bilateral symmetry
Eggs of the elephant louse are attached to the fur of elephants. The parents use a sculpturing or a plumelike process to embed the eggs into the skin. The eggs are singularly attached to the host by a drop of waterproof glue (Grzimek 1972). The base of the egg and hair shaft is surrounded by this glue to keep it stationary. The zygote inside the egg develops into a nymph and hatches from the egg and joins the adults in feeding immediately (Grzimek 1972). The nymphs resemble adult elephant lice and have the same habits as well. With age, the louse molts, but little change in appearance occurs (Grzimek 1972).
