Today's pteropod phylum Pleistocere Lip-foot subclass Worms worms. It is yellowish-grey in color, most notably characterized by 15 pairs of footlets, usually inhabiting human houses or near wet dead wood, with strong environmental adaptability. Commonly found in China are the flower worm, the great worm and the black spotted worm. Adult worms are about 25 to 50 mm long, have a hard shell on the dorsal plate, the 15 pairs of feet of the worm are long and fragile, the feet close to the head are relatively short, and these feet become longer in the order of the tail, and the last pair of feet is the longest, called feet. The numerous feet of the worm cooperate with each other when they move, allowing them to move through walls, ceilings, floors and grass at a very fast speed, up to 15 lengths per second, and up to 15 lengths without injury. Outdoors, worms like to live in wet and cold places, mostly under large rocks and crevices, in wood piles and dead leaf piles; indoors, worms can live almost anywhere, especially in damp places such as basements, bathrooms and toilets.
It is mainly composed of 6 parts: head and poisonous fangs, antennae, dorsal plate, web plate, 15 pairs of foot walking feet and internal organ mass. There are two antennae at the very front of the head of the worm, which are basically the same length as the body length, and the whole antennae are gradually tapered from the root to the end, the root diameter is about 220um, and the end is extremely thin and soft. The antennae of the worm are segmented whip-like structures, which play a role in feeling the temperature and humidity, odor and mechanical vibration in the environment in survival, and are important organs for the worm to find a habitat and identify the dangers in the environment. Compared with the web, the epidermis of the dorsal plate of the worm is harder, and there are 2113 pores in the dorsal plate, which is an important organ of the snake's breathing.

Worms like to drill holes, it can be said that there are holes that must be drilled, so if people do not pay attention, it will cause worms to snuck into the ears. After the worm enters the ear, it can lead to the development of a disease such as otitis, which can lead to more serious diseases if left untreated. And worms can also transmit many diseases, and they are also poisonous. After the sting of the worm, it initially becomes a translucent blister, and then becomes a cloudy pus or blood, with a pronounced red halo around it, and the vesicle wall is often scratched or scratched to form an erosion surface, if there is a secondary infection, it is very similar to gangrenous zoster, with itching and pain.
