What invertebrate groups come under the heading of arthropods and what does the word arthropod mean?
arthropod. / (ˈɑːθrəˌpɒd) / noun. any invertebrate of the phylum Arthropoda, having jointed limbs, a segmented body, and an exoskeleton made of chitin. The group includes the crustaceans, insects, arachnids, and centipedes.
Which 4 categories of invertebrates are arthropods?
Arthropods are divided into four major groups:
- myriapods (including centipedes and millipedes);
- arachnids (including spiders, mites and scorpions);
- crustaceans (including slaters, prawn and crabs).
Which of the following invertebrates are examples of arthropods?
The following families of organisms are all examples of arthropods:
- Insects such as ants, dragonflies, and bees.
- Arachnids such as spiders and scorpions.
- Myriapods (a term which means “many feet”) such as centipedes and milipedes.
- Crustaceans such as crabs, lobsters, and shrimp.
Are all arthropods invertebrates?
Arthropods is a phylum that includes insects and spiders. They are invertebrates, which means they do not have an internal skeleton and backbone. Instead, they have a hard exoskeleton on the outside, the top layer of which is known as the cuticle. The cuticle is made out of proteins and is very versatile.
Which of the following groups includes only arthropods?
Leech, butterfly, silverfish.
Are arthropods invertebrates?

Arthropods is a phylum that includes insects and spiders. They are invertebrates, which means they do not have an internal skeleton and backbone.
What are arthropods invertebrates?
Arthropods are invertebrate animals with an exoskeleton, segmented body, and jointed appendages. The phylum Arthropoda includes insects, arachnids, myriapods and crustaceans. Arthropod species make up more than 80% of all living animal species.
What is the exoskeleton of arthropods made up of?
The exoskeleton is composed of a thin, outer protein layer, the epicuticle, and a thick, inner, chitin–protein layer, the procuticle. In most terrestrial arthropods, such as insects and spiders, the epicuticle contains waxes that aid in reducing evaporative water loss.
Which one of the following are examples of Arthropoda?
Cockroach, scorpion, prawn are a few examples of the arthropods. Note: As the arthropods have segmented bodies, exoskeleton, and jointed limbs, thus chitin is present in exoskeleton or cuticles and also a polymer of glucosamine is present.
