The main difference between Worm and Insect is that the Worm is a animal that typically has a long tube-like body and no legs and Insect is a class of invertebrates. Worms are many different distantly related animals that typically have a long cylindrical tube-like body and no limbs.

No, worms are not insects. Insects belong to a large grouping of animals with jointed exoskeletons, called arthropods (meaning jointed foot). The earthworm belongs to a different grouping, the segmented worms or annelids.

Earthworm, also called angleworm, any one of more than 1,800 species of terrestrial worms of the class Oligochaeta (phylum Annelida)—in particular, members of the genus Lumbricus.

Worms are members of several invertebrate phyla, including Platyhelminthes (flatworms), Annelida (segmented worms), Nemertea (ribbon worms), Nematoda (roundworms, pinworms, etc.), Sipuncula (peanutworms), Echiura (spoonworms), Acanthocephala (spiny-headed worms), Pogonophora (beardworms), and Chaetognatha (arrowworms).

Do worms have brains? Yes, although they are not particularly complex. Each worm’s brain sits next to its other organs, and connects the nerves from the worm’s skin and muscles, controlling how it feels and moves.

If an earthworm is split in two, it will not become two new worms. The head of the worm may survive and regenerate its tail if the animal is cut behind the clitellum. But the original tail of the worm will not be able to grow a new head (or the rest of its vital organs), and will instead die.

Some species can release a stinging substance. Earthworms and red wriggler worms are perfectly safe to hold bare-handed, though it’s probably prudent to wash your hands before eating your next meal. Centipedes can bite, but they are nearly impossible to catch, which works out well.

But animals with simple nervous systems, like lobsters, snails and worms, do not have the ability to process emotional information and therefore do not experience suffering, say most researchers.

In Worm Loves Worm two worms fall in love and decide to get married. Cricket Beetle Spider and the Bees all want to help out but as they start to plan the wedding they keep tripping over details. We all know that earthworms don’t get married.

According to new research studying neurons within microscopic roundworms, the answer is an emphatic ‘yes’. Its 302 neurons and 7,000 synapses are comparatively tiny compared to the 86 billion neurons and 100 trillion synapses in a human brain.

Thinking and feeling: Worms have a brain that connects with nerves from their skin and muscles. Their nerves can detect light, vibrations, and even some tastes, and the muscles of their bodies make movements in response. If worms dry out, they suffocate.

“Worms do not possess any sense of hearing,” Darwin wrote. Darwin went on to say that worms, while stone-deaf, are very sensitive to vibrations and pulled back into their burrows when their pots were placed on top of the piano that was then played.

Extra: Earthworms are blind, but they have special cells that can sense light.

Keeping Worms Happy

1. Worms need to live in a warm, dark place. Red wigglers like the temperature to be between 40-75 degrees.
2. Worms need moisture in their environment. The texture of their bedding should feel like a wrung-out sponge.
3. Worms need air. Worms breathe through their skin!
4. Worms need food!
5. Worms need to wiggle!

Do earthworms have eyes? No. They have receptor cells in their skin that are sensitive to light and touch. They will move away from light because heat from the sun or a light source will dry out their skin and kill them.
