About 84 percent of all known species of animals are members of this phylum.
Arthropoda is the largest phylum with about nine lakh species. They may be aquatic, terrestrial or even parasitic. They have jointed appendages and a chitinous exoskeleton. This phylum includes several large classes and contains the class Insecta which itself represents a major portion of the animal species in the world.
Oct 4, 2019 · Arthropods are a lineage of life that developed skeletons on the outside – their hard shells, made of a material called “chitin” – instead of on the inside for structural support.

Aug 3, 2023 · Arthropoda (Arthropods) Definition. Arthropods are bilaterally symmetrical, triploblastic, metamerically segmented animals with coelom which is reduced and modified. Their body is covered externally in a chitinous exoskeleton which molts periodically and their appendages are joined.
What is an arthropod? Arthropods are invertebrates that have exoskeletons, aka external skeletons. They belong to the phylum Arthropoda which is the largest phylum in the animal kingdom and makes up at least 84% of all animals on the planet. Arthropods have segmented bodies and jointed appendages.
arthropod, Any member of the largest phylum, Arthropoda, in the animal kingdom. Arthropoda consists of more than one million known invertebrate species in four subphyla: Uniramia (five classes, including insect s), Chelicerata (three classes, including arachnid s and horseshoe crab s), Crustacea (crustacean s), and Trilobita (trilobites).
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.
