The world's most abundant creature , MaLu
Both the margaret and the centipede belong to the polypoda of the arthropod phylum, but malu belongs to the pluripod order, and almost all tyrannosaurs have 2 pairs of feet; Centipedes belong to the order Lip and Foot, with 1 pair of feet per body segment. In terms of appearance, Malu's foot count is far more than that of centipedes. Centipedes are also called "centipedes"; Malu, on the other hand, is a "millipede", which is currently known to be the most abundant creature in the world.
Our common horses are slow-moving, prefer dark and humid environments, mostly feed on humus, and live in bark, leaf litter, under rocks, and soil layers. However, there is also a special class of horses, which are widely distributed in dark caves, generally living on the surface of caves, or creeping on rocks, feeding on humus, soil particles, animal feces or animal carcasses, which we call cave horses.

The mainland is the country with the largest karst distribution area in the world, and the cave horse land is also rich in species, but the research started late. The earliest reported cave malu on the mainland is the long thorny dragon malu, which was discovered in 1960. At present, there are more than 12,000 species of horse land known worldwide, and only about 300 species have been recorded on the mainland, of which about 100 species of caves belong to 13 families.
The biological characteristics of Malu
Malu is divided into three stages: eggs, larvae and adults. Within a year, after 7 to 10 moltings, the number of feet and body segments increases accordingly, that is, molting stops.
Common land-based adults generally have a body length of 20 to 60 mm, round and slightly flattened, and the body is divided into two parts: the head and the trunk. It consists of many body segments, with a calcareous dorsal plate on the back.
The head segment contains antennae, the single eye is very large, the palate is paired, and the eyes are polyocular. The number of body segments varies depending on the type.
1 pair of genital foramen, at the base of the 2nd pair of feet. The female is white, spherical, and covered with a transparent sticky substance.
The amount of eggs laid by a single female is usually around 300 eggs. Under suitable temperature conditions, the larvae hatch in about 20 days, and develop into sexually mature individuals after several months, surviving for more than 1 year.
Horse-land is moist and yin, mainly plant-fed, prefers to eat scamores, and sometimes damages the young roots of plants and young seedlings and young stems and leaves.
It mostly inhabits soil blocks on moist arable land or in piles of dead branches and leaves.
The number of individuals in malu varies significantly with time, and on sunny days, adult malus are diurnal and nocturnal, and occasionally a small number of individuals are active on the ground during the day. In rainy weather, the group can move on the ground throughout the day, showing obvious surface aggregation. Between June and October, the nights are best after the rains from summer to early autumn. When the horse land enters the breeding period of one year and one generation, the female horse land lays eggs in piles under the grass in the damp shade, in the stone crevices, and under the soil blocks in the surface layer of the field, in the soil crevices.
Malu generally endangers the young roots and young seedlings and young stems and young leaves of plants, which occur in various parts of the country, in addition to the lawn, the victim plants also include cyclamen, melon leaf chrysanthemum, orchid, clematis fern, begonia, hanging bell begonia, Wenzhu and some other flower plants.
But it also contributes, Malu is not only an important decomposer and ecological hero of the forest ecosystem, but also a raw material for Chinese medicinal materials. Malu does not bite, but please do not easily touch it, because Malu will also protect itself, in the outside touch will secrete toxins that cause local irritation, severe can cause obvious erythema, herpes and necrosis. Kids be careful! In addition, if people accidentally eat Malu by mistake, it will also cause lip edema.
Although Malu is non-toxic and does not sting people, it also has defensive weapons and skills. As soon as it is touched, it will immediately curl up into a ball, stand still, or roll away in the same direction, and then slowly stretch out and crawl away after the danger has passed. Millipedes have stink glands on their body segments that secrete a poisonous odorous liquid that smells so bad that both poultry and birds dare not peck at it.
