The first pair of feet of centipede are hooked and sharp, and there are poisonous gland mouths at the hook ends, which are generally called palatal teeth, claws or poisonous limbs, and can discharge poisonous juice. After a centipede is bitten, its venom gland secretes a large amount of venom, which is injected into the skin of the bitten person along the mouth of the venom gland of the palatine tooth, causing poisoning. The general length is between 1.5 mm and 34 mm. Medicinal centipede is a large lipped polypod with only 2/kloc-0 pairs of walking feet and/kloc-0 pairs of jaw feet. Chikawa, a close relative of centipede, has only 15 pairs of walking feet and 1 pairs of jaw feet. "Stone centipede" has only 15 feet. Some centipedes have very short feet, including 35 pairs and 45 pairs, and the most reach 19 1 pair. Centipede is afraid of the sun. It doesn't sleep during the day and comes out at night. It likes to live in a dark, warm, rain-proof and ventilated place. They mainly live in low mountainous areas with little soil and rocks. Although distributed in plain areas, the number is small. Scolopes likes to live in hilly areas and sandy land. During the day, they often lurk in the cracks of masonry, under the roots of walls, and in the dark corners of piles of leaves, weeds and rotten wood. At night, they come out to feed on caterpillars, spiders and cockroaches. Generally, when the weather turns cold in May 438+1October in June, they dig holes into the soil on the hillside facing the sun, and lurk in the soil about 12cm deep from the ground. After the winter solstice (early March), as the weather gets warmer, they will move to feed.
Centipede has a strong ability to drill seams. It often uses its sensitive tentacles and flat head plate to explore joints, and most of the gaps between rocks and land can pass through or inhabit. When the density is too large or disturbed too much, it can cause cannibalism and even death. However, under the condition of artificial breeding, dozens of fish can live together with sufficient bait and drinking water. Centipede is a typical carnivorous animal, fierce and has a wide range of foods, especially small insects. It has a jaw that can shoot venom and can even kill animals bigger than itself. There is also the phenomenon that the same species kill each other and are poisoned. The insects eaten by centipedes include crickets, locusts, scarabs, cicadas, grasshoppers, all kinds of flies and bees, and even edible spiders, earthworms, snails, frogs, mice, birds, lizards and snakes that are much larger than their bodies. When food is scarce in early spring, you can also eat a small amount of grass and moss buds. When raised artificially, the food is fresh and will not be eaten if it is slightly rotten. Centipede is a hermaphrodite animal, and the identification of male and female is of great significance to the reasonable collocation of male and female, reducing the expenditure of raising male centipede and improving the reproductive rate. The male and female identification of centipede is complicated, which can only be determined by comprehensive analysis of head, body shape and constitution. The head is flat and big, the back of 2 1 joint is flat and round, large and wide, the abdomen is thick and soft, and the female squeezes the reproductive region of the tail with her hand to expose it. The hump of the head is oval, and the rear edge of the 2 1 segment backboard is slightly hump-shaped, sharp, small and narrow, with a thin abdomen and a hard body. Males have l pairs of degenerated reproductive limbs in the tail reproductive region.
