What is an Arthropod?

What is Arthropod's jointed appendages?
Arthropod's appendages of different segments are variously adapted for walking, feeding, sensory reception, swimming and defense. Thanks to the evolutionary flexibility of their segments and appendages, it contributes to the great diversification of arthropods.
What is the diversification of Arthropods?
The estimation about the total arthropod population numbers is a billion billion individuals, but only a million species has identified, mostly insects. They must be regarded as the most successful animal phylum.
