In French, centipede also has the name "Bach Tuc" which means thousands of feet. However, this does not mean that centipedes have thousands of feet. Most centipedes have 30-50 feet, but there are also species with numbers up to 350 feet.
The centipedes are usually brown in color, a combination of red and brown colors. Because almost all centipedes live in the ground and narrow, less sun-filled slots. Therefore they are less pigmented and often have a dark color. However, there are species that live in the tropics and lots of sunshine are brighter and more colorful.
Centipedes have many different sizes. It may be several millimeters or even up to 30 centimeters. Virtually every centipede earth appears in many different areas and environments. It can be said that their living environment is very diverse.
Currently there are 8000 known species of centipedes in the world. However, only 3000 species have been carefully described by science. It is not exaggerated to say that the habitat of the centipede is also exaggerated, as even in the arctic circle, they are walking around. The most humid or habitat environment is underground, vegetation in the tropical rainforest, decaying leaves, ...
It can be said that centipedes are the largest invertebrate predators on land. They also contribute a lot to this earth's biomass.
Learn about centipedes - Life cycle and reproduction
The process of reproduction and fertilization of centipedes does not require mating. The male simply creates a sack and lets the female pick it up. In some centipedes, the semen is placed in a net bag and the male performs a flirtatious dance to persuade his children to receive his pouch. For some other species, the males produce the semen and then leave, letting the females find it for themselves.
In temperate areas, the breeding time of centipedes takes place in spring and summer but in subtropical and temperate areas it seems that centipedes do not have a seasonal breeding cycle. At the same time, some centipedes are monogamous. For Lithobiomorpha and Scutigeromorpha sets, scrape the dug into a small hole, lay eggs in it and then fill it up and leave. Number of eggs ranges from 10-50 fruits. The time of "hatching" eggs lasts depending on the species, maybe from 1 month to several months.
Sexual maturity is not the same, such as S. coleoptera which takes up to 3 years to mature sex, while Lithiobiomorpha in suitable conditions takes only 1 year. Compared to insects, fairly long-lived centipedes, such as Lithobius forficatus can live up to 5 or 6 years.
Due to the low number of eggs produced, the time of hatching and the maturity of sexual maturity, many opinions suggest that centipedes are animals belonging to the selected group. more children. Each litter lays 15-60 eggs in a nest in a tree trunk or humus. After laying, remove the remaining side of the nest, keep an eye on the eggs, lick off the eggs to protect them from fungal infections; After the eggs hatch they continue to watch the children until the centipedes can establish themselves - the time with their children can last up to 1 year.
However, in some cases, maternal centipedes can eat eggs or leave eggs infected and die. Some centipedes of Scolopendromorpha have a real sample behavior, ie a voluntary mother centipede to give birth to their newborn babies. Craterostigmomorpha's reproductive life cycle and behavior have not been revealed until now.
Through the above article, we can know that centipedes are animals that are dangerous to human health if they encounter them. Therefore, we need to prevent them in particular and other harmful insects in general.
