In taxonomic disciplines over 1.1 million arthropods have been named and described, and current estimates suggest millions more species have yet to be described, particularly amongst the insects.
NO. Arthropods do not have a 4 chambered hearts.
The phylum arthropoda takes its name from the Greek for "jointed foot" or jointed leg; arthropods are characterized by their jointed appendages.
Arthropoda. :P
its an Arthropod
Anthropods (humans) do not have wings; not to be confused with phylum Arthropoda (arthropods). Many arthropods have wings (insects are arthropods, including flying insects), but, of course, not all of them.
Those are Spiders!

Not all arthropods use spiracles to obtain oxygen, but many do. Spiracles are openings on the exoskeleton that lead to a network of tracheae, allowing gas exchange. Aquatic arthropods, such as many crustaceans, typically use gills instead of spiracles for respiration. Therefore, while spiracles are common in terrestrial arthropods, they are not universal among all arthropods.
Only some arthropods have a cephalothorax, like for example the lobster. Other arthropods have functionally separate (or non-fused) head and thorax, like many insects.
All insects are arthropods. The phylum Arthropoda contains the classes Insecta (insects), Crustacea (crabs, lobsters, etc), Chelicerata (arachnids) and a few others.
They express the characteristics inherent to arthropods. All insects are arthropods. Not all arthropods are insects.
Arthropod comes from the Greek meaning "jointed feet", which is what arthropods have, as well as an external skeleton, which they shed when growing.
