The largest phylum in kingdom animalia is arthropoda. The word meaning of the term arthropoda is jointed appendages. Animals in this phylum have jointed appendages. This phylum includes the class insecta which are the animals with three pairs of legs. Arthropoda consists of animals that have their body covered by a chitinous exoskeleton which is for protection. Sensory organs of these animals include eyes, antennae, and statocysts. Examples of insects are beetles, fly, dragonfly, cockroach, etc. Ticks and mites are animals that belong to the class Arachnida. Spiders and scorpions belong to this class of animals. Most of the animals in class Arachnida have eight legs. They are different from insects as most of them lack antennae or wings.
