Question

Why arthropoda is considered the largest phylum?

Answer 1

The phylum Arthropoda consists of more than 75% of the animal species found on this earth. The reasons for the success of arthropods are as follows.

i. Jointed legs that allow more mobility on land

ii. Hard exoskeleton made of chitin that protects the body

iii. The hard exoskeleton also reduces water loss from the body of arthropods making them more adapted to terrestrial conditions
