Difference between poisonous and non-venomous snakes

Identifying the difference between poisonous and non-poisonous snakes will not be too difficult if you know the general characteristics of both. Snakes are vertebrates and belong to the Reptilia Class. Reptiles are able to live in various habitats and have three basic characteristics, namely;
(a) reproduce by laying eggs,
(b) have dry skin
(c) do chest breathing.

What are Venomous Snakes?

Venomous snakes are capable of producing venom. Examples of venomous snakes include cobras, vipers and related species. Some snakes have very strong venom while others to a lesser degree. Snake venom glands are actually modified salivary glands. Venomous snakes inject venom through their fangs. Therefore, the presence of fangs is a typical characteristic of venomous snakes. Most more 'sophisticated' snakes including vipers and elapids have tube cavities within their fangs to inject venom more effectively.

What are Non-Poisonous Snakes?

Snakes that are unable to reproduce can be known as non-venomous snakes. Most snakes fall into this category. Some examples of non-venomous snakes include phytons, boas, anacondas, etc However, bites from large non-venomous snakes can be very painful and may be fatal due to their strong jaws. Nonvenomous snakes can be easily identified by the absence of fangs, round heads, and the presence of anal scales in two rows. Since these snakes do not have venom, they use other methods such as coiling around their prey to paralyze it.
