CHARACTERISTICS 

     Measurement of H. gammarus is 60 cm in length and weighed 6 kilograms of lobster meat and has a clearly visible a pair of claws. Lobster develop in total length by shedding off their own hard external skeleton ( rigid external covering for the body) , a progression described as moulting. After they shed off their hard external skeleton, the body tissues will absorbed a water which can cause a lobster swelling and burst their external skeleton. After it has been separated by itself, further more swelling appears and a newer external skeleton gets started in order to turn solid form. 

HABITAT AND LIFE SPAN

      H. gammarus (European lobster) , closest related and also practically similar to the biggest lobster of H. americanus (American lobster) , resides in the oceans within the north-eastern of Atlantic. European lobsters are found from Norway to Morocco,within the North Ocean, in the western and also central regions of the Mediterranean sea, and in western places within the Black Sea during a lobster season.

     Compared with the American lobster, in which generally identified for displaying off reddish and reddish-brown colours, the European lobster often is known as appearing quite blue in color. H. gammarus could be potentially live over a less or more of 15 years.

PREDATORS AND DIET

      Young lobsters tend to be hunt and kill for food upon by a large number of fish and mainly aquatic group Crustacea such as a large marine fish (cod), wrasse, snakelike fish, flatfish, shore crabs ,bigger lobsters and brown crabs. Adult lobsters are incredibly belonging to the most significant ocean invertebrates and are an unlikely prey for the majority of ocean creatures due to their sheltering ,nocturnal behavior and preventive claws. 

      Apparently, investigation indicates that the measurement of the lobster’s claws is imbalance to the size of their prey and that instead of being adapted for forage or predator protection, they might be more related to produced, occurring, or existing within a species competition for shelter, food, mates and also as any notice indication of power . A diet for H. gammarus including a smaller lobsters, crabs and larger mollusks.
