Oct 25, 2024 · Arthropod, 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. Learn more about arthropods in this article.

Arthropods have an exoskeleton made principally of chitin—a waterproof, tough polysaccharide composed of N-acetylglucosamine. Phylum Arthropoda is the most speciose clade in the animal world , and insects form the single largest class within this phylum. For comparison, refer to the approximate numbers of species in the phyla listed below.
Arthropoda is the largest animal phylum with the estimates of the number of arthropod species varying from 1,170,000 to 5~10 million and accounting for over 80 percent of all known living animal species. [33] [34] One arthropod sub-group, the insects, includes more described species than any other taxonomic class. [35]
Arthropods are the largest phylum in the animal kingdom. Most arthropods are insects. The phylum also includes spiders, centipedes, and crustaceans. The arthropod body consists of three segments with a hard exoskeleton and jointed appendages. Terrestrial arthropods have adaptations for life on land, such as trachea or book lungs for breathing air.
Arthropods have probably always dominated the animal kingdom in terms of number of species and likely will continue to do so: An estimated 85 percent of all known species are included in this phylum! In effect, life on Earth could conceivably be called the Age of Arthropods beginning nearly 500 million years ago.

May 6, 2024 · The largest known arthropod species, also a water scorpion, is the fossil Jaekelopterus rhenaniae, which measured nearly 2.5 meters (8 feet) in length. While large terrestrial arthropods, like adult insects and spiders , do not usually exceed 100 gm (0.22 lbs), sometimes the larvae of Megasoma actaeon , a variety of rhinoceros beetle, weigh more than 200 gm (0.44 lbs).
