Arthropods (/ ˈ ɑːr θ r ə p ɒ d / ARTH-rə-pod) 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 segments, and paired jointed appendages.
Jun 20, 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.
Oct 4, 2019 · Arthropods colonized land about 100 million years before vertebrates did. It’s thought that colonizing land was easier for them for several reasons – including the fact that they had already evolved legs, which they used for walking on the bottom of the sea.
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.
Arthropods are not only the largest phylum of invertebrates. They are by far the largest phylum of the animal kingdom. Roughly 80 percent of all animal species living on Earth today are arthropods.
Arthropods are invertebrates with jointed legs. They make up about 75% of all animals on Earth and have a major role in maintaining ecosystems as pollinators, recyclers of nutrients, scavengers and food for other animals.
Jun 20, 2024 · The numbers and diversity of arthropods are enormous and they are found in almost all of the habitats that cover the Earth's surface. Arthropods are of great importance to humans in the form of food, medicine, and agriculture, and generally as major links in food chains.
All arthropods are bilaterally symmetrical and possess a segmented body covered by an exoskeleton containing chitin, which serves as both armour and a surface for muscle attachment. Each body segment may bear a pair of jointed appendages.
Jan 19, 2021 · Arthropods come in almost every shape and color imaginable. And they can be found in diverse environments, from the ocean deep to dry desert to lush rainforest.

Essentially, arthropods are characterized by possessing jointed limbs and an exoskeleton. They are the most successful animal Phylum on the planet, in regards to population size and species diversity. There is thought to be over 2 million types of arthropod in today’s world.
