How To Identify A Snake Or Worm?

Snakes and worms are found throughout the world, making their way around by wriggling and slithering with long cylindrical-shaped bodies. Worms vary greatly in size, but the snakes that look like worms tend to be larger in the United States.


One of the easiest ways to differentiate between a snake and a worm is to look at the body. While coloration may be similar in some species, snakes have scales where worms tend to have segmented bodies and can breathe through their skin.

The snakes that look like worms tend to search for moist soil, while the worms excrete mucus, which keeps them moist and helps them to breathe.


The snakes that look like worms are mostly blind and rely on their tongues, which they flick in and out, to taste the air and find prey. They also rely on vibrations, while the worms use a number of sensory organs.

Earthworms have light and touch-sensitive cells on the front f their bodies to help them navigate.


Earthworms tend to be a pink/gray color, while the snakes that look like worms can range from tan to dark brown and black.

Are They Venomous?

The snakes that look like worms are non-venomous snakes and are not dangerous to humans. Many will try and bite, which will be superficial with their tiny mouths and teeth. Some will push the tip of their tail into your hand as a defense mechanism, also not dangerous.

They can be handled and relocated safely, but some do give off a foul odor, used to deter predators.

What Do They Eat?

The snakes that look like worms tend to eat a varied diet, depending on the species. Their diets range from earthworms and centipedes to slugs, small insects, insect and slug eggs, and larvae.


If you are worried the worm you found in your yard is actually a snake, the good news is that the snakes that look like worms are harmless to humans and don’t tend to come inside the home. They hide during the day and come out at night, so they are seldom encountered.
