and Lobsters belong to the phylum Euarthropoda.
Euarthropoda includes insects (like Grasshopper),
myriapods, arachnids and crustaceans (like Lobsters). Common characteristics
are exoskeleton (external skeleton), a segmented body, and paired jointed
appendages. Their body is enveloped with cuticle made of chitin, which is often
mineralised with calcium carbonate.
