What tool can cause an open wound?

After being bitten by a snake, the shape of tooth marks is eight-shaped, and those with small tooth spacing are non-toxic. There are many kinds of snakes, which can be divided into poisonous snakes and non-poisonous snakes.

Generally, poisonous snakes have two long sharp fangs, which are used to store their toxins and inject them when biting their prey. So if you are bitten by a poisonous snake, there are only two fangs left alive. Non-toxic snakes don't secrete toxins, and naturally they don't need teeth like syringes to help themselves. So after being bitten by a non-toxic snake, there are usually two rows of tiny teeth marks on your body.

A poisonous snake has fangs and glands, while a non-poisonous snake has no fangs and glands. No poisonous snake has many teeth, except the upper and lower collar teeth, as well as the teeth of jawbone and pterygoid bone. In addition to the above teeth, poisonous snakes also have 2 14 special teeth, which are large in shape, with grooves and cavities in the upper clavicle, and the base is connected with poisonous glands, which are called fangs.
