Arachnids are classified in the Phylum Arthropoda, which also consists of crustaceans, insects, centipedes, and millipedes. Arthropoda is treated here as a monophyletic clade of genetically diverse but evolutionarily linked species. 2. Their bodies are covered with the hard shell made up of chitin, forming and exoskeleton. These jointed appendages variously specialized for feeding, locomotion, sensing . Phylum Arthropoda includes animals that have been successful in colonizing terrestrial, aquatic, and aerial habitats. This phylum is commonly called sponges.

It is estimated that about 84% of all known species of animals belong to this phylum and number of known species vary between 1,170,000 and 5 to 10 million. The single-celled condition is an important feature which sets the protozoa apart from all other animals.
