Question

What are the reasons that you can think of for the arthropods to constitute the largest group of the animal kingdom?

Answer 1

The phylum Arthropoda consists of more than two-thirds of the animal species on earth. The reasons for the success of arthropods are as follows:

• Jointed legs that allow more mobility on land.
• Hard exoskeleton made of chitin that protects the body.
• The hard exoskeleton also reduces water loss from the body of arthropods making them more adapted to terrestrial conditions.
