There are more than 4,400 different living types of worms, which is way too many to list here, but the most common types are earthworms and inchworms. Nightcrawlers are the most common earthworms in the U.S., while palouse are at the other end of the spectrum, being the least common type of earthworm. The cankerworm is one example of the many species of inchworm. Another common type of worm is the intestinal worm.
More than 2,700 species of earthworms exist, which makes them the most common type of worm on earth. Earthworms live in trees, under rocks, and can often be found near water. As their name suggests, these worms live in the soil of the earth. During the winter, they stay warm by burrowing deep into the ground and come back up to the surface in spring when the ground warms up. Earthworms are essential to plant life, as their holes and tunnels in the ground provide pathways for water to reach the plant roots in the ground.
Nightcrawlers are the most common type of earthworm in the United States. They are frequently used as fishing bait and are distinguished by their long bodies, which can grow more than a foot long. Their bodies are split by a thick band in the middle, and they need cool environments in order to survive.
The rarest type of earthworm is called the palouse, which can be found in small parts of Idaho. These worms are set apart from other earthworms due to their light skin coloring and their enormous 3-foot (about 1-m) long bodies. The palouse worm also has a distinct flowery smell about it.
The second most common type of worm is the inchworm, which has 1,200 different species. Inchworms are indigenous to North America and are the larvae of Geometridae moths. They get their name from the fact that they often grow up to an inch long. These worms are smooth and hairless and have three pairs of legs at the front of their bodies and two to three pair of legs at the back of their bodies. These extraordinary creatures can stand erect when in danger.
One interesting type of inchworm is called the cankerworm, or measuring worm. These worms can produce a thin line that is sometimes made of silk, similar to a spiderweb. The threads are often produced when the worm has to drop from a tree in order to evade a predator. Cankerworms come in a variety of colors, but they all have distinctive long horizontal stripes on their bodies. The cankerworm is one of the most destructive to crops, as it prefers to hide in apple trees, elm trees, and other fruit trees.
Many people are put off by all types of worms, but none so much as the human intestinal worm. There are many species of worm that infest the human body. Pinworms, tapeworms, and roundworms are some of the most common. Other types of intestinal worm include roundworms, hookworms, and the most common, giardia intestinalis.
