First, for the purposes of this question, I am narrowing the analysis to Jews who keep kosher, e.g. follow the dietary laws, and also ignoring any personal Allergies.
Prawns are explicitly prohibited as they are sea creatures without fins and scales.
Crab meat is not kosher.
In order to be kosher, food has to be prepared according to the kosher-laws (see Deuteronomy ch.14). These are explained in detail in the Talmud-volume of Chullin.
* Meat must be from those land animals which have split hooves and chew their cud (such as beef, venison and mutton).
* Fish have to have scales and fins. Shellfish are not kosher.
* Birds cannot be among those listed as forbidden in the Torah (Deuteronomy ch.14) and cannot be hunters/scavengers. In actual practice, today we eat only those species concerning which we have a tradition that they're permitted, such as domestic chicken, geese, pigeons and turkey.
* Animals must be slaughtered in the manner specified by Jewish law and must be free of all disease. In actual practice, those who keep kosher purchase meat which is certified as having been prepared in the kosher manner.
* As much blood as possible must be removed from meat before cooking, since consumption of blood is forbidden (Leviticus ch.17). This is done at home or by the kosher butcher, through salting, soaking and rinsing.
* Dairy and meat cannot be combined in the same meal and there's a waiting period between eating one and then the other. After dairy: 1/2 hour. After meat: 6 hours for most Jewish communities.
* Fruits and vegetables should be checked to be sure they're free of bugs. Some Jews avoid cauliflower, asparagus, and the like, because of the difficulty in checking them.
Additionally, food must be prepared and handled following kashrut-laws and with kosher ingredients only. Any food that does not meet these requirements cannot be eaten by those who are religiously observant. Foods which are purchased should be labeled as having had kosher supervision during their processing.

... or shrimps, or lobster. Well, I hope that won't be too simple an answer, but crab and other shellfish aren't kosher because fish have to have both easily removed scales and fins.
They're shellfish.
lobster is not kosher. it is shellfish.
No, lobster is not kosher. The reason for this is that aquatic animals must have both fins and easily removed scales in order to be kosher.
No, lobster is an animal.
No because the lobster has a hard shell
the country, as a rule, does not eat lobster - in as much as a country cannot eat (although I hear that they can consume) but people in the UK do indeed eat lobster and many other forms of marine life.
One can eat lobster in Maine in almost any restaurant as lobster is one of their greatest resources. Some of the best places are Five Islands Lobster Co., Bagaduce Lunch and Waterman's Beach Lobster.
