Clawed lobsters comprise a family (Nephropidae, sometimes also Homaridae) of large marine crustaceans. They are important as an animal, a business and a food.
In Biology
They are not to be confused with spiny lobsters, which have no claws (''chelae''), and are not closely related. The closest relatives of clawed lobsters are the reef lobster ''Enoplometopus'' and the three families of freshwater crayfish.
Smaller varieties are sometimes called "lobsterettes". Lobsters are invertebrates, and have a tough exoskeleton, which protects them. Like all arthropods, lobsters must molt in order to grow, leaving them vulnerable during this time. Lobsters are considered a food delicacy around the world. In Europe, they are extremely expensive; in some parts of North America, much less so.
Lobsters live on rocky, sandy, or muddy bottoms from the shoreline to beyond the edge of the continental shelf. They generally live singly in crevices or in burrows under rocks.
Lobsters are primarily scavengers, feeding on mollusks and decaying animal matter, but will also eat live fish, dig for clams, and feed on algae and eel-grass. An average adult lobster is about nine inches (230 mm) long and weighs 1.5 to 2 pounds (700 to 900 g). Lobsters grow throughout their lives, though, and are long-lived. They can thus reach impressive sizes. According to the Guinness World Records, the largest lobster was caught in Nova Scotia, Canada and weighed 20.14 kg (44.4 lb).
The environmental conditions of the lobsters can vary from ocean to ocean, but the lobster's temperature environment does not fluctuate much since their home is large mass of water, the ocean.
Like all arthropods, lobsters are largely

Needs work
This page needs work, I think there's a template for taxonomic information out there somewhere. Anyone want to take a crack at it?

Removed paragraph
Moved this paragraph from the article, it seems debatable at best, and no evidence is cited. How do you quantify the ocean bottom being a more competitive than, say, the African savannah? --Lexor|Talk 04:23, 20 May 2004 (UTC)
:''Lobsters truly define the statement of “survival of the fittest” from Charles Darwin’s theory of evolution. Only the biggest and the fittest survive the ocean bottom because it is a fierce world with fierce competition. Those that survive end up on dinner plates. ''
langoustine redirect
Hi,
Langoustine redirects to this page, but I'm not sure it should do so. Unfortunately this seems to be a language issue!
According to http://gourmet.sympatico.ca/fish/lobster/scampi.htm a langoustine is what is known as scampi in the USA. In England it is the same thing as a Norway lobster.
I know a langoustine as an animal about 6 inches long and looking like a cross between a shrimp and a lobster.
Can someone tidy this?
Cheers!
As far as I can tell, scampi is the same thing as langoustine (in the UK) - both refer to the Norway lobster, also called Dublin bay prawn, ''Nephrops norvegicus''. This may also be what you describe as being like a lobster-shrimp cross; certainly ''Nephrops'' is slimmer than a ''Homarus''-lobster. I think a separate page for ''Nephrops'' would be justified, and that Langoustine should redirect there.

legs
Hi,
Does anyone know how many legs a lobster has, and is it always that same number for any lobster? Would you count the claws as legs (i.e., did they evolve into claws?)?
Thank you.
Lobsters are of the order 'decapoda', the anthropods with ten legs. Not all lobsters have claws (eg California spiny lobster),
Lobstering
Lobstering a type of escape reaction in some crustaceans
Antarctic Krill can evade predators by very fast backward swimming (lobstering), flipping its telson. They reach speeds of over 60 cm per second. The trigger time to optical stimulus is in spite of the low temperatures only 55 milliseconds.
Spiny Lobster
''Jasus''
''Linuparus''
''Palinurellus''
''Palinurus''
''Panulirus''
Spiny lobsters, also known as rock lobsters are a family (Palinuridae) of about 45 species of achelate crustaceans, in the Decapoda Reptantia. Sometimes, spiny lobsters are, confusingly, called ''crawfish'' or ''sea crayfish''.
Although they superficially resemble true lobsters in terms of overall shape, and having a hard carapace and exoskeleton, the two groups are quite unrelated. Spiny lobsters can be easily distinguished from true lobsters by their very long, thick, spiny antennae, and by their complete lack of claws (''chelae''); true lobsters have much smaller antennae and claws on the first three pairs of legs, with the first being particularly enlarged. Like true lobsters, however, spiny lobsters are edible and are an economically significant food source; they are the biggest food export of the Bahamas http://www.internationalreports.net/theamericas/bahamas/2003/thespiny.html 1.
The furry lobsters (''e.g.'' ''Palinurellus'') are sometimes separated into a family of their own, the Synaxidae, but are usually considered members of the Palinuridae. The slipper lobsters (Scyllaridae) are their next closest relatives, and these two or three families make up the Achelata. Genera of spiny lobsters include ''Palinurus'' and a number of anagrams thereof: ''Panulirus'', ''Linuparus'', ''etc.'' (Palinurus was also a helmsman in Virgil's Æneid.)
Spiny lobsters are found in almost all warm seas, including the Caribbean and the Mediterranean, but are particularly common around Australasia (''Jasus novaehollandiae'' and ''Jasus edwardsii'') and South Africa (''Jasus lalandii''). Spiny lobsters tend to live in crevices of rocks and coral reefs, only occasionally venturing out at night to seek snails, clams, crabs, sea urchins or carrion to eat. Sometimes, they migrate ''en masse'', in long files of lobsters across the sea floor. Potential predators may be
Lobster Hand
Lobster hand is a rare congenital deformity of the hand where the middle digit is missing, and the hand is cleft where the metacarpal of the finger should be. This split gives the hands the appearance of lobster claws.
It is an inherited condition, and often occurs in both the hands and the feet. Its pattern of inheritance is autosomal dominant, though occasionally it can skip a generation.
It affects about 1 in 90,000 babies, with males and females equally as likely to be affected.
It is treated surgically to improve function and appearance. Prosthetics may also be used, and genetic counselling given to parents with the condition.

American Lobster
The American lobster is a species of lobster (scientific name ''Homarus americanus''), also known as the northern lobster, or the Maine lobster. They thrive in cold, shallow waters where there are many rocks and other places to hide from predators. Lobsters are solitary and nocturnal.
Found along the coast of North America as far south as North Carolina, they are famously associated with the colder waters around the Canadian Maritimes, Newfoundland and Labrador and Maine, where they can grow to enormous sizes. They commonly range from 20cm to 60cm in length and 0.5kg to 4kg in weight, but have been known to reach lengths of well over 1 meter and weigh as much as 16kg.
The adult lobster's main natural enemy is the codfish, but other enemies include haddock, flounder, and other lobsters. Overfishing of cod in the early 20th century has allowed the lobster population to grow enormously.
Molting and Mating
Lobsters shed their shells 2-3 times per year while juvenile, but only once a year or less often when fully mature, about 4 to 7 years old. When the lobster gets near its next shedding period, it will start to grow a new shell underneath the current one. The outer shell will become very hard and darken, becoming covered with black marks that look like scratches. (They are now known, very unimaginitively, as hardshells.) The line that runs along the back of the lobster's carapace will begin to split, and the two halves of the shell will fall away. Claws and tail will be pulled out from the old outer shell, as the inner shell is very malleable. The old shell is often eaten for calcium recovery and the leftovers are sometimes buried.
Females can only mate right after molting, but larger females can store sperm for several batches of eggs from a single coupling. All females store the sperm to fertilize eggs later, not at the time of copulation. While getting ready to molt the female will find the den of
