Arthropods ( / ˈɑːrθrəpɒd /) are invertebrates in the phylum Arthropoda. They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated ( metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which ...

Mar 26, 2024 · arthropod, (phylum Arthropoda), any member of the phylum Arthropoda, the largest phylum in the animal kingdom, which includes such familiar forms as lobsters, crabs, spiders, mites, insects, centipedes, and millipedes. About 84 percent of all known species of animals are members of this phylum. Arthropods are represented in every habitat on ...
A body layout that is the reverse of ours. An arthropod’s brains is in its head, but its nervous cord runs along its belly and its food passage (stomach, intestines, etc.) runs along its back. Since the brain (above the mouth) connects to the nervous cord (below the mouth), the brain actually surrounds the esophagus.
Likewise, the relationships between various arthropod groups are still actively debated. Today, arthropods contribute to the human food supply both directly as food, and more importantly, indirectly as pollinators of crops. Some species are known to spread severe disease to humans, livestock, and crops. (Full article...

Scientists know of more than 1 million speciesof arthropods. 80% of all known animal species are arthropods. Many more species have not yet been described. 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 ...
Arthropods have a hard exoskeleton. The exoskeleton reduces the loss of water (dessication). This helps them to live on land without drying out.
Arthropods are made up of four groups of living animals and one group of extinct animals: 1. Chelicerates include mites, horseshoe crabs, scorpions and spiders. 2. Myriapods include millipedes and centipedes. 3. Crustaceans include barnacles, crabs, shrimp, crayfish, and lobsters. Most crustaceans live in water, with the most notable exception of w...

They possess an exoskeleton with a cuticle made of chitin, often mineralised with calcium carbonate, a body with differentiated (metameric) segments, and paired jointed appendages. In order to keep growing, they must go through stages of moulting, a process by which they shed their exoskeleton to reveal a new one. They are an extremely ...
You are familiar with a wide variety of arthropods from seeing them in your daily life. Have you thought about what they all have in common? Arthropods are a lot more than just delicious feasts and disgusting pests. Before we go too far, we need to figure out exactly what an arthropod is. In this section, we will explore these key questions:
