Identifying an oriental venomous snake.

 

We often search for the techniques to differentiate the venomous and non-venomous snake. The result we found are mostly describing that the snake with triangular head and vertical eyes is venomous, and the rest are non-venomous. This technique is not suitable for oriental as well as African snake. It is useful for Europe and American snakes, as these countries consist of only venomous viper. Triangular head and vertical eyes are the characteristics of a venomous snake. There are so many medically important snakes present, excluding vipers, in oriental and African region. So, the techniques can be atrocious for enthusiast and can cause accident for misidentification.  There are simply no easy techniques for identifying venomous snake. It is better to have an idea on venomous snake in your area.


Here are some techniques to identify a venomous snake of oriental region.

  1.   Hooded snakes are venomous. Ex: cobra (Naja), king cobra: (Ophiophagus hannah).

  2.  Vipers are venomous. They consist of triangular head and vertical eyes. They are relatively bulky. Ex:  Green Pit Viper (Trimeresurus). Russell’s viper (Daboia Russelii) is often misidentified as a baby python.

  3.           Kraits are venomous. They consist of round head and pupil. They can be totally black with white ventral portion or black with white or yellow bands. Ex: common krait, black krait, banded krait.

  4. Sea snakes are always venomous. They hardly bite a man.

  5.          Coral snakes are venomous. They are short, thin and very colorful. Their occurrence is very rare. Hence, they are medically less significant.
