The longest scorpion on earth is the African Scorpion, which can reach a total length of 9 inches. There are over 1,300 species of scorpions worldwide.

Mesosoma : The front half of the abdomen is made up of six segments. the mesosoma is armored by an extra layer. This extra layer is made up of chitinous plates, which are the plates usually found in the cell walls of fungi, and the exoskeletons of insects and arachnids.

 

Metasoma : This is the scorpion’s tail, and the second half of its opisthosoma. A scorpion’s sting is made up of six segments, ending in the telson, or the sting.
