all arthropods are not insects because.. Arthropods aka the Phyla Arthropoda consists of 4 classes. (yr 1 university level here :D ) they are the Crustacea arachnida myriapoda and as you said the insecta. ok so these CLASSES are well defined by the characteristics the organisms of the class bear in common. hence one should not confuse the insect class with the phyla arthropods because one is a main category whilst one is a sub category which aid in defining the main category as a whole. hope this was helpful.

∙ 6y agoThey're invertebrates because they don't have an internal skeleton - like humans and mammals do. Instead, they have an external covering - called an exo-skeleton.
By definition an invertebrate is an organism with no vertebra (backbone, spine). Arthropods don't have them nor need them as they use an external skeleton (exoskeleton) made from a hard protein (chitin), to provide the same functions as internal skeletons (endoskeletons) on vertebrates.

arthropods
What is an arthropods features?
Arthropods are characterized by segmented bodies, an exoskeleton made from chitin, and joint appendages.
What characteristics do all arthropods share?
Arthropods have segmented bodies, an exoskeleton made from chitin, and joint appendages. They also have an internal body cavity (hemocoel) and an open circulatory system which employs hemolymph.
Are there any invertebrates that aren't arthropods?
Arthropods are only one group of invertebrate animals. There are many other invertebrates in the world. Some examples would include single-celled animals, worms, jellyfish, gastropods like slugs and snails, and echinoderms like starfish and sand dollars. Most animals in the world are, however, in the arthropod category. WikiAnswers

How numerous are invertebrates?
most invertebrates are arthropods, and 70% of animals in the world are arthropods (insects), so I'm guessing there are more invertebrates than vertebrates.
How are arthropods different from invertebrates?
Arthropods are invertebrates. An invertebrate is an animal without an internal skeleton and that's exactly what an arthropod is.
