10 of the world’s smallest snakes that are often mistaken for worms

When we think about snakes, we usually picture the big ones– like pythons, anacondas, or cobras. These are the snakes that often make headlines because of their size and power. But there’s another side to the snake world that most people don’t notice.

Hidden under the ground, beneath leaves, or inside tiny burrows are snakes so small that they can easily be mistaken for earthworms.

These tiny snakes may not look scary, but they’re fascinating in their own way. They’ve adapted to live in small spaces, feeding on insects and termites, and they quietly help keep nature in balance. Here’s a look at ten of the smallest snakes in the world– each one small but truly special.
Ringneck Snake
Found across North America, from Canada to central Mexico, the ringneck snake is small but eye-catching because of the bright ring around its neck. It grows to about 9–10 inches long and has mild venom that it uses to catch small animals like frogs, lizards, and salamanders. It’s harmless to people and has a smart trick to scare off enemies– it curls its tail to show a bright red underside.

Malagasy Blind Snake
This tiny snake lives in Madagascar and is part of the blind snake family. It can grow up to 10 inches long and has a pink, see-through body with a tough, shovel-like head that helps it dig in sandy soil. It spends most of its life underground, eating ants and termites. Because it’s only found in limited areas, it’s considered critically endangered.
Short-Headed Garter Snake
Found in parts of New York and Pennsylvania, this garter snake is around 10 inches long. It lives in open grassy places and eats mostly earthworms. It’s calm and rarely bites, though it may release a bad smell when it feels threatened. Females give birth to live young, sometimes every year or every other year.
Lined Snake
The lined snake lives in the Great Plains and nearby regions and grows between 8 and 15 inches. It prefers grasslands and woodlands and mainly eats earthworms and slugs. After mating in autumn, females give birth to live babies in late summer. The young snakes are independent from birth.

Peters’ Thread Snake
Native to southern Africa, this small snake is about 8–11 inches long. It has a shiny, dark body and tiny eyes. It lives mostly underground and eats termites and their eggs, often staying near termite nests. Sometimes, it comes out after heavy rain. Even though it’s harmless, it’s often mistaken for a venomous species called the burrowing asp because they look alike.
Flat-Headed Snake
At just 7–8 inches long, this snake is one of the smallest in Missouri and nearby states. It has smooth tan or reddish-brown scales and a pink belly. It likes sandy soil and spends most of the day hiding, coming out to eat insects, larvae, and centipedes. Females lay a few eggs in early summer, and babies hatch by late August.
Texas Blind Snake
Found from Kansas to Mexico, this snake grows between 4 and 11 inches long and looks a lot like an earthworm. It hides under rocks, logs, or in the soil, eating ants, termites, and insect eggs. Though it’s called “blind,” it can still sense light and dark. Females lay a few soft eggs, and the species is not considered at risk.

Variegated Snail-Eater
This small snake from the Amazon region grows just over 3 inches long. It has a blunt head, large yellow eyes, and grayish-black markings. It mainly eats snails and slugs, pulling them out of their shells with its tiny teeth. It’s active at night and rests under leaves during the day.
Brahminy Blind Snake
Also known as the “flowerpot snake,” this species has spread across many parts of the world through soil and potted plants. It originally came from Asia and Africa and grows only 2–6 inches long. It’s the only snake species made up entirely of females– it reproduces without a male. It eats ants, termites, and insect larvae, helping keep the soil healthy.
Barbados Threadsnake
This is the smallest snake in the world, growing only about 4 inches long. It’s found in the Caribbean, especially in Barbados, and lives under rocks, feeding on termites and ant larvae. The female lays just one egg at a time, and the baby snake is already half the size of its mother.
