The phylum Arthropoda consists of about 80% of the total animals in animal kingdom. The reasons for arthropods being the largest group are as follows:
i. Joint legs allow more mobility on land.
ii. Hard exoskeleton which is made up of chitin protects the body.
iii. The hard exoskeleton reduces water loss from the body and thus making them more adapted to terrestrial conditions.
