Snakes are probably the most feared reptiles all over the world. The species is synonymous with both, fear and mysticism. The oriental and occidental cultures have viewed this reptile in different light. However, today there is a marked paradigm shift in the way we look at snakes. The awareness campaigns and the education offered by the various dedicated institutions have made a remarkable difference to the way our children learn to relate to the species. The education includes a strong identification with the physical characteristics and the inherent nature of snakes.

Colour and pattern are the most specific characteristics that help to identify the content of venom in a snake. However, they are also the two most difficult characteristics to describe. In addition, we have to consider that most snakes have different colours and patterns on their backs and bellies.
Colour is a frequently used descriptor which indicates whether a snake is poisonous or not. It is believed that the darker the shade, the more venom. Many different colours and shades are found in some snakes. In the case of some snake species, the colour of the head may be in stark contrast to that of the body and this is one of the primary 'venom distinction' characteristic.
