The hard upper shell covers the N. norvegicus's cephalothorax (the merged head and thorax of an arthropods), although the abdominal area is long and divided into segments, ending from a large tail fan. 

      The first 3 pairs of legs attach a claws, which the first are significantly pointed and bear side rails of spines. N. norvegicus have 2 pairs of antenna (a pair of long, thin sensory appendages on the heads of an arthropods), the second is the longer and thin. There is a long, spinous rostrum ( a beaklike projection, especially a stiff nose or anterior prolongation of the head in an arthropods), and the compound eyes (kidney-shaped).


HABITAT AND LIFE SPAN


      N. norvegicus are generally small and a bit sensitive. This type of lobster species have a claws which is have length like their body part. Approximately, 17 types of scampi species are existing all over the world where they live and inhabits in waters such as the eastern coastline bridging North and South America, Europe oceans , Western African coastline, Western edges of Australia and Southeast Asia during a lobster season. They could be have a potentially to live for 5 to years and in exceptional cases they could live almost 5 years.

       N. norvegicus spending a lots of their time in burrows / holes and they only coming out to find a food and seek out a mate. They are an opportunistic predators ( they take instantaneous advantages of any kind of situation that benefits them. 


      As a predator, they capture, prey and attack however being opportunistic and also they scavenge because it is easier than hunting), mostly feeding on crustaceans (an arthropod from the large,mostly marine group Crustacea, for example a crab, lobster, shrimp), mollusks ( octopuses, snails, slugs, mussels) and polychaete worms. N. norvegicus is a scavenger and predator that makes small foraging activities,mostly during a night. 


      They will feed on active prey, including fish and worms, which they capture with their chelipeds (1 of the pair of legs that has the large chelae in decapod crustaceans) and walking legs, and food is conveyed to the mouth with the front walking legs, assisted by the maxillipeds (an appendage modified for feeding, situated in pairs behind the maxillae).
