Python is the largest primitive snake in the world, with traces of belt and hind legs. There is an obvious distance between the degenerated cutin of the hind limbs near the anus of the male snake, but the degeneration of the female snake is easily overlooked. In addition, it has a pair of developed lungs, but advanced snakes only have 1 or 1 degenerated lungs. Python's body surface pattern is very beautiful, symmetrically arranged into large patches like clouded leopard, with black or white spots around the edge. The scales are smooth, the back is light yellow, taupe or brown, and the patches at the back of the body are very irregular. Python's head is small and black, with a black spot at the back and under the eyes, yellow and white below the throat, and no obvious differentiation of abdominal scales. The tail is short and thick, very tangled and aggressive.

Python belongs to arboreal or aquatic snakes, living in tropical rain forests and subtropical humid forests, and is an omnivorous snake. They mainly feed on birds, rodents, small wild animals, reptiles and amphibians, with sharp teeth and quick and accurate hunting action, and sometimes enter village farmhouses to prey on poultry and livestock; Sometimes male pythons hurt people. Laying eggs in April every year, and laying eggs in June. Each egg lays more than 8-30 eggs, many of which can reach 100. These eggs are rectangular, and each egg has a "small tail" the size of a duck egg. Each egg weighs about 70-100g, and the incubation period is about 60 days. After laying eggs, female pythons have the habit of hatching on eggs. At this time, if you get close to it, it is easy to hurt people.
