The Viper is a highly venomous snake species with a large venom gland giving the head a broad, triangular shape. Vipers can control the movement of their fangs, sometimes using only one of the fangs to inject their venom. Viper teeth are huge and hollow, filled with venom. It can be seen that the viper is still very poisonous.

In addition to understanding the toxicity of the viper, let's talk about the internal structure of the viper. The internal structure of the viper is divided into ten parts: skin system, skeletal system, muscular system, respiratory system, digestive system, cloaca system, nervous system, sensory organs and chromosomes.
