First, let us start with the venomous ones. These species can be found in the Eastern Ghats of India, and the names are Bamboo Pit Viper (Trimeresurus gramineus), Saw Scaled Viper (Echis carinatus), Russell’s Viper (Daboia russelii), Banded Krait (Bungarus fasciatus), Common Krait (Bungarus caeruleus), Hook-nosed Sea Snake (Enhydrina schistose), Spectacle Cobra (Naja naja) and King Cobra (Ophiophagus Hannah). 

Next, moving on with the non-venomous ones, the list comprises of Barred Wolf Snake (Lycodon striatus), Bronze-back Tree Snake (Dendrelaphis tristis), Common Wolf Snake (Lycodon capucinus), Indian Rock Python (Python molurus), Vine Snake (Ahaetulla nasuta), Red Sand Boa (Eryx johnii), etc.

Individuals who walk in deep water may experience a bite but are unsure whether it had been made by a snake or not. It can be because of some other creature as well. However, there are some specific snake bite signs which you must put attention to. For instance, a pair of puncture marks, swelling and redness around the bite area, extreme pain at the wound site, feeling of nausea and vomiting, shortness of breath or difficulty in breathing in severe cases, enhanced salivation and sweating, blurred vision, etc.

Ans: It is quite interesting to study the anatomy and physiology of a snake. All organs, right from the brain to the gastrointestinal tract, fit into the body of a snake in a horizontal fashion. All organs are designed in a flat structure to fit in the body of the snake easily. Snakes lack any limbs in them. The heart of snakes is divided into three divisions, two of which are atria and one ventricle.

Ans: Snake charmers are the entertainers who muse the audience by holding snake shows. They control the snake's movements with the help of musical instruments, leaving the viewer in awe. They are said to have originated in India in ancient times. Many regard them as sacred as well. Snake charmers do not kill snakes. Instead, they protect them and carefully displace them in the jungle areas far from the crowded areas so they are not killed or harmed. 

Ans: The most ridiculous myth associated with snakes is that they drink milk. This is completely inappropriate as snakes don't drink or lick milk. They feed on other things and milk is surely not a part of the menu. Other myths are that snakes move in pairs, they engulf each other in stressful situations, and seeing golden snakes will make you rich out of nowhere. All these myths shouldn't be believed. 

Ans: No, not all of them are poisonous. Some are non-poisonous as well. India is home to four species of poisonous snakes. Cobra is the most common among them. Despite being poisonous, not all of them will bite you unnecessarily. It is because they are afraid of the bigger creatures as well. Also, they have a significant amount of poison in them, which cannot be used all at once or frequently.

Ans: If you believe the sound of the instrument hypnotizes snakes, then you are wrong. Snakes do not hear anything as they do not have ears for the same. The circular and spiral motions of the pungi made by the snake charmer are observed by the snakes. As a result, the snake tries to follow the movements of the pungi, and the audience assumes the snake charmer to be some magician for doing so.
