Clawed lobsters comprise a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans. Highly prized as seafood, lobsters are economically important, and are often one of the most profitable commodities in coastal areas they populate.

Though several groups of crustaceans are known as lobsters, the clawed lobsters are most often associated with the name. Clawed lobsters are not closely related to spiny lobsters or slipper lobsters, which have no claws (chelae), or squat lobsters. The closest relatives of clawed lobsters are the reef lobsters and the three families of freshwater crayfish.

The fossil record of clawed lobsters extends back at least to the Valanginian Age of the Cretaceous.

Lobsters are invertebrates with a hard protective exoskeleton. Like most arthropods, lobsters must molt in order to grow, which leaves them vulnerable. During the molting process, several species change color. Lobsters have 10 walking legs; the front three pairs bear claws, the first of which are larger than the others. Although, like most other arthropods, lobsters are largely bilaterally symmetrical, they often possess unequal, specialized claws, like the king crab.

Gordon James Ramsay, OBE (born 8 November 1966) is a British chef, television personality and restaurateur. He has been awarded 13 Michelin stars in total and currently holds 12.

Ramsay is known for presenting TV programmes about competitive cookery and food, such as the British series Hell's Kitchen, The F Word, Ramsay's Best Restaurant, and Ramsay's Kitchen Nightmares, along with the American versions of Hell's Kitchen, Kitchen Nightmares, and MasterChef.

Gordon Ramsay was born in Johnstone, Renfrewshire, Scotland, and raised in Stratford-upon-Avon, Warwickshire, England from the age of 5. Ramsay is the second of four children; he has an older sister, Diane, a younger brother, Ronnie, and a younger sister, Yvonne. Ramsay's father Gordon (died 1997) was, at various times, a swimming pool manager, a welder, and a shopkeeper; his mother, Helen Cosgrove, and Yvonne have been nurses. Ramsay has described his early life as "hopelessly itinerant", as his family moved constantly due to the aspirations and failures of his father, who was violent. In 1976, they finally settled in Stratford-upon-Avon where he grew up in the Bishopton area of the town. In past public interviews, Ramsay has declined to describe his father as an alcoholic; however, his autobiography, Humble Pie, describes his early life as being marked by abuse and neglect from this "hard-drinking womaniser". At the age of 16, Ramsay moved out of the family house into a flat in Banbury.
