No, worms are segmented invertebrates and insects belong to the animal kingdom.
Comparison of animals and insects
Animals, like humans, have backbones (vertebrae) . Insects do not.This is one significant difference between animals and insects. Animals have a system of glands which help them digest food; while an insect has a more simple opening that functions in place of a stomach for dissolving food before it moves on to other parts of the body. In addition, animals have separate breathing structures from their digestive tract; whereas insects breathe through tubes along its body length which also serve to transport fluids throughout the body. Insects depend on various systems such as water drawn up with leaves or moisture within wood to keep them hydrated. Some animals use the water in their surroundings to stay hydrated, but others have developed other ways of keeping themselves moist or damp which are not so similar to how insects do it.
Animals are able to move around by contracting muscles . Insects have a hard exoskeleton , so they can’t contract their muscles.
Insect legs have three segments. Animals usually have two, but sometimes have more. Insects also have antennae , which are their sense organs. Most animals don’t have that feature on their face or head, but some do such as horses and cows that use them to smell for danger. In some cases the mouth of an insect is part of the first segment of its body, but in most cases it is not. Insect mouths are part of their head or thorax . Animal mouths are usually separate, on their face.
Animal bodies have blood which flows through the body to carry nutrients and oxygen throughout different parts of their system. But insects do not have blood flow through their systems. They have a tubular heart that pumps fluid into spaces between the muscles and tissues.
Insects breathe through their skin. Animals do not. Insects also have a complete digestive system, with a mouth, esophagus , stomach, intestines , anus , etc., while animals only eat food to swallow it and then it goes to the stomach, where it breaks down and is absorbed.
Animals reproduce by mating . Insects also reproduce by mating, but unlike humans they do not have the same reproductive organs that are required for reproduction; instead they produce sperm or eggs through modifications of their digestive system. Animals usually bear live young (viviparous) , while insects produce eggs (oviparous) . Animals also feed their young with milk, while insects produce a substance that is similar to honeydew or licked-up plant sap for their young.
Insects have compound eyes and 3 simple eyes called ocelli on the top of their head. Most animals have two of each kind of eye, but some animals such as mammals or birds have lost their 3rd ocelli.
Insects do not have lungs like humans and other vertebrates do. Instead they breathe through spiracles which are openings in the insect’s side that lead to tubes called tracheae . Insects can be quite small (1 mm) with only a few spiracles, but other insects such as beetles have many. Some insects such as cockroaches and dragonflies can take in oxygen through holes all over their body.
Insects almost always have 6 legs , though some centipedes and millipedes may have more than that because they count the legs on each of their segments which is why they have so many different numbers of them. Animals usually have 4 legs or 2 legs, but some animals such as kangaroos and horses that walk on their hind legs only have 2 feet while walking with all fours.
