The Spot-tailed Pit Viper, scientifically known as Trimeresurus erythrurus, is a venomous snake found in Southeast Asia. These snakes belong to the Viperidae family and are characterized by their distinct appearance, potent venom, and preference for forested habitats. In this article, we will discuss various aspects of the Spot-tailed Pit Viper in detail.
The Spot-tailed Pit Viper is a medium-sized snake, with adults measuring around 60-80 cm in length. The body is stout and cylindrical, with a short tail. The head is triangular, and the eyes are relatively large. The pupils are vertical, and there is a pit between the eye and nostril that is used to detect prey.
Scalation:
The scales of the Spot-tailed Pit Viper are keeled, meaning they have a raised ridge along the center. They have 21-23 rows of dorsal scales and 150-160 ventral scales. The subcaudal scales are paired, and the anal plate is single.
- They have keeled scales, which means each scale has a raised ridge or keel running along the center.
