Classification: Animalia, Arthropoda, Crustacea, Malacostraca,Decapoda, Nephropidae, Homarus, Homarus Americanus
Homarus: Lobster species, a genus.
Nephropidae: Marine crustaceans having stalked eyes, long antennae, and five pairs of legs, the first pair of which is modified into large pincers.
Decapoda: Order of crustaceans with "ten legs" consisting of Crayfish, Lobster, Crabs, and Shrimps.
Malacostraca: Class of marine crustaceans and amphipods including those listed above and krill, they are distinguished by their Bauplan, a segmented body consisting of twenty parts.
Crustacea: a subphylum of arthropods distinguished by their double jointed limbs and naupilus form of larvae.
Arthropoda: Phylum of organisms with no vertebral column and a rigid exoskeleton/
Animalia: Multi-cellular eukaryotes.
The American Lobster is a member of a diverse category of marine species known as Homarus, which possesses no vertebral column. Instead, they maintain their rigid figure with a hard exoskeleton.

The Cambrian explosion which occurred about half a billion years ago gave rise to the genus of arthropoda in which lobsters are a subcategory. Arthropods are classified by the presence of a rigid exoskeleton on their outer body and a segmented body. they include spiders, insects, crustacean and trilobites. More specifically, Hexapoda, Trilobite, Chelicerata, Myriapoda,Crustacean, and Marrellomorph. As lobsters evolved, there bodily segments fused together as a result of staying in the ocean, in addition, they developed a system of molting for growth that let them shed their rigid exoskeleton (cuticle) and grew a new, larger one.
