Arthropod exoskeletons are made of cuticle, a non-cellular material secreted by the epidermis. Their cuticles vary in the details of their structure, but generally consist of three main layers: the epicuticle, a thin outer waxy coat that moisture-proofs the other layers and gives them some protection; the exocuticle, which consists of chitin and chemically hardened proteins; and the ...
A typical arthropod exoskeleton is a multi-layered structure with four functional regions: epicuticle, procuticle, epidermis and basement membrane. Of these, the epicuticle is a multi-layered external barrier that, especially in terrestrial arthropods, acts as a barrier against desiccation.
Most arthropod species are insects. "Insects are the most diverse organisms in the history of life". Most arthropods live on land. The phylum Arthropoda is the only phylum of invertebrates that mostly live on land. But crustaceans (crabs, shrimp and their relatives) mostly live in water.

Arthropoda is the phylum for aw the Arthropod speshie. Arthropoda is in the domain eukaryots, the kinrick Animalia, the subkinrick Eumetazoa, an the superphylum Ecdysozoa. Arthropods haes exoskelets, lithed bodies, an lithed limms. Some o the maist weel-kent arthropods is insects, speeders, an trilobytes. Subphylum Trilobitomorpha

An arthropod (/ ˈ ɑːr θ r ə p ɒ d /, from Greek ἄρθρον arthron, "joint" and πούς pous, "foot" (gen. ποδός)) is an invertebrate animal having an exoskeleton, a segmented body, and paired jointed appendages. Arthropods form the phylum Euarthropoda, which includes insects, arachnids, myriapods, and crustaceans.
Artropodele (din greacă arthron, "articulație" și podos, "picior") sunt animale nevertebrate, ce au membrele articulate.Încrengătura include insecte, milipede, centipede, arahnide, crustacee etc. Artropodele sunt organisme cu un exoschelet (schelet extern), corp segmentat și membre (apendice) anexate de cap și torace.
