Snakes are scaly, legless reptiles that slither across the ground and constantly taste the air by flicking out their forked tongues.
Some types are venomous,including:
- Coral snakes.
Most species of venomous snakes are pit vipers, which can navigate their environment and hunt using infrared-sensing receptors that allow them to detect the heat of their prey.
Venomous and non-venomous snakes have differing characteristics, which makes them easy to distinguish.
Venomous Snake Appearance
All venomous vipers have triangle-shaped heads and pits between their eyes and nostrils containing infrared-sensing organs. Most venomous species also have elliptical-shaped pupils as opposed to the round pupils found in other snakes. Western rattlesnakes are easy to identify due to the distinctive rattle at the end of their tail, which they shake when threatened to warn of their presence.
Non Venomous Snakes
The majority of snakes found in the United States are not dangerous and are in fact quite beneficial, such as the common eastern garter snake, which preys upon small rodents like mice and rats.
Non Venomous Snake Appearance
Eastern garter snakes are non-venomous and therefore have narrow heads and lack the extra sensory receptors of pit vipers. They are typically black in color with three bright yellow stripes running the length of their bodies. Some snakes may grow several feet in length, while others can be quite small, never reaching more than a few inches.
Usually dark areas
Almost all snakes adapt to suit specific habitats, and most have certain requirements that dictate where they prefer to live. Most species live in dark, damp areas with plenty of cover, such as in wood piles, un-mowed lawns with tall grass, beneath overgrown shrubbery, near pond banks, within heavily mulched flower beds, or even in unkempt basements.
