The shape of the tiger-spotted neck snake is green on the back of the head, green and black on the back of the upper lip scale, and yellow and white on the lower lip scale. At present, there is a black stripe between the 4th and 5th upper lip scales, and there is also a black stripe obliquely reaching the corner behind the eyes. The back of the body is mainly green or grass green, with black and orange spots on both sides of the front section alternating with each other, and there is an obvious neck groove in the middle of the neck.

The tiger-spotted neck snake has poisonous glands and larger teeth behind the tooth slot, which is very similar to the venomous snake in the posterior sulcus. However, the tiger-spotted neck snake is not a poisonous snake, because there is no catheter communication between its poisonous glands and fangs.

Extended data:

The venom of the replanted snakes does not pass through the fangs, but enters the bodies of other animals by other physical means. The tiger-spotted neck-grooved snake is highly toxic, and it is a snake that is enough to cause danger to human beings. Japan did report a case of being bitten to death by a tiger-spotted neck snake. There are also many cases of danger caused by this kind of snake bite in China.

However, although the tiger-spotted neck snake can secrete toxins, it will not cause fatal damage. This is because the posterior sulcus teeth of this snake are very short, and behind the mouth, they generally don't bite deeply, so the posterior sulcus teeth can't bite people.
