Are red snakes poisonous?

I believe everyone is familiar with the animal snake. Its appearance is very scary. There are many types of snakes, with great differences in color and size. In many people's minds, snakes with brighter colors are usually poisonous. For example, bright colors like red make everyone think that red snakes are poisonous. So, is this really the case? Are red snakes poisonous? Let’s take a closer look below.

How to identify poisonous snakes and non-venomous snakes? Most people only distinguish them based on whether their heads are triangular, their tails are short and thick, or their colors are bright, which is not comprehensive enough. Although the head of venomous snakes is a distinct triangle, some venomous snakes do not have a triangular head; while among non-venomous snakes, the false pit viper has a triangular head. The tails of five-step snakes, belly snakes and cobras are indeed very thick, but the tail of the iron-headed snake is relatively slender; many brightly colored snakes, such as the jade-spotted rat snake and the fire chain snake, are not venomous snakes, and the color of the pit viper is like mud or dog shit, which is not very eye-catching, but it is very poisonous. Therefore, the distinction between venomous and non-venomous snakes is mainly based on the following points:

1. Venom glands: Venomous snakes have venom glands, while non-venomous snakes do not. Venom glands evolved from salivary glands. Located on both sides of the head, behind the eyes, hidden in the jaw muscles, and can secrete venom. When a venomous snake bites something, the muscles surrounding the venom gland contract, and the venom is injected into the body of the bitten object through the venom duct and the tube or groove of the fangs, causing poisoning. Non-venomous snakes do not have this function.

2. The venom duct is a pipe that transports venom, connecting between the venom gland and the fang. Only venomous snakes have venom ducts.

3. Venomous snakes have fangs, which are located in front of or behind the non-venomous teeth on the upper jaw and are longer and larger than the non-venomous teeth.

I think everyone should have a clear understanding of whether red snakes are poisonous. You can judge whether a snake is poisonous simply by its color. It is best to combine it with the shape of the snake's head, so that the accuracy will be higher. Since many snakes are highly poisonous, in our daily lives, if we encounter snakes that we are not familiar with, it is best not to touch them casually.
