Arthropods are the most biologically successful group of animals because they are the most diverse and live in a greater range of habitats than do the members of any other phylum of animals.
How many classes are in arthropods?
The phylum Arthropoda is commonly divided into four subphyla of extant forms: Chelicerata (arachnids), Crustacea (crustaceans), Hexapoda (insects and springtails), and Myriapoda (millipedes and centipedes).
What criteria do biologists use to classify arthropods into 4 subphyla?
What characteristics do biologists use to classify arthropods? Arthropods are classified based on the number and structure of their body segments and appendages—particularly their mouthparts.
