B aliumip (B aliumip), known as "earth clam" and "land planarian", is a relatively low terrestrial flat animal, planarians, diplodocus family, belongs to the flat animal phylum. Its head is fan-shaped, its body is flat and undisciplined, and its sides are symmetrical. Generally, the body length is 20 to 30 cm, and the length can reach more than 60 cm. Feeding on small animals and organic matter in the soil, there is a nickname called earthworm killer, after encountering earthworms, it is killed, and then it secretes digestive juices, which are used in the opening in the middle of the body to suck but this body is flat. It breathes through the skin and moves against the tiny cilia on the body, which move very slowly. When stimulated, it is also possible to perform a squirming like a locust to escape. Planarian leeches are hermaphrodites, and hermaphrodites are relatively inferior animal features, referring to an animal that has both male and female sexual organs. Interestingly, this animal has a strong regenerative ability, such as being cut in half, both halves can regenerate the lost other half, forming two new complete individuals.
Planarians: Most species live freely, with cilia on the surface of the body and well-developed glandular cells in the epithelial cells. The digestive system, nervous system and senses are more developed. Marine species such as planarian flat-horned planarians, freshwater species such as planarians, and planarians live on moist land.
