The porcupine, also known as the spiny pig, is the same animal. The porcupine is a kind of rodents covered with spikes, which can be used to defend against predators. The porcupine is usually brown, gray and white, with a stout body, with a body length of 50-75cm and a weight of10-18kg. The upper body is covered with hard spines, and the spines in the limbs and abdomen are short and soft; The thorns on the buttocks are the longest, about 300 mm; The tail is very short, hidden in the buttocks with long thorns, and the whole body is brown and black.

Spines are generally spindle-shaped, hollow, milky white in color, with light brown in the middle 1/3, and there are many slender longitudinal stripes on the surface of thorns. I sleep in caves during the day and come out to look for food at night. I like to eat peanuts, sweet potatoes and other crops. When frightened, the thorn in the tail immediately stands up and swish to warn the enemy.

Pig, besides being a delicious dish, is also a respectable animal, and it has many unknown facts. Pigs have a keen sense of smell and can be trained as "truffle pigs" to find truffles buried in the ground, and can also be used as sniffers for mines; Pigs have about 15000 taste buds, compared with adults who usually have 2000 to 4000, which makes pigs have the ability to taste tens of thousands of flavors, while we only have thousands.

Pigs only walk on their toes, not with their whole feet. The outer toes are used for balance, not for exercise. The sound of a pig is louder than that of a motorcycle, which can reach1115 decibels, while the engine of a motorcycle can only reach about 100 decibels, so the sound of a pig is undoubtedly harsh.
