Lobster

hi I don't know five but i know 1. is they have claws to protect from predators and to help them grab things, 2. is they can camouflage themselves to hide from predators and possibly to catch prey.

The thin appendages that extend from a lobster's head are called antennae (antennas). As with insects, these appendages are used to sense the lobster's environment, making the name "feeler" appropriate.

Don't cook them when they are still alive.

If you take a chef's french knife and put where the tail and the body come together

and insert and cut down through head...it kills them almost instantly...yes, I know, crude, but consider the alternative.

Perhaps cooked lobster could keep up to four days in the refrigerator, but it would be best to use within a day or two. How long it lasts will depend upon the quality of the lobster to begin with and the handling.

The lobster is an arthropod, and all arthropods belong to the taxonomic domain of Eukarya.Eukarya covers all organisms in the Kingdom Animalia, as well as the Kingdoms Plantae, Fungi and Protista.

Homarus is a genus of lobsters, which include the common and commercially significant species Homarus americanus (the American lobster) and Homarus gammarus(the European lobster).[1] The Cape lobster, which was formerly in this genus as H. capensis, was moved in 1995 to the new genus Homarinus

I have read in The Secret Life of Lobsters that lobstermen in Maine try hard to be sustainable. There are regulations in place, like no eating egg bearing or v-notched (formally egg bearing) lobsters. there is a very specific range of lobster sizes that are legal to eat. Based on this info, I think they are a sustainable seafood choice. More sustainable seafood choices would be farm raised fish, clams or shrimp.

Maryland for sure with old bay r da best Maryland or Maryland-Virginia... it really depends on what is meant by "produces." They are Chesapeake Bay blue crabs and you can get good ''Maryland-style'' Chesapeake Bay steamed crabs anywhere in the DelMarVa region (Delaware, Maryland, Virginia) plus of course Baltimore, Annapolis etc.

The largest lobster known on record was caught on 12 February 1977 in Nova Scotia, Canada. It weighed 20.14 kg, or 44.3 lbs, and was between 90cm and 120 cm long. (Most adult lobsters weigh between 800 grams and 1.4 kilograms). There are estimates that it could have been 100 years old.

No. Squid are saltwater creatures, and crayfish live in freshwater.

A langosta has no claws and a lobster does.

Crabs and lobsters are arthropods. In colloquial speech the term "bug" generally refers to arthropods on land, mostly insects and arachnids.

In scientific terms the only true bugs are insects in the order hemiptera, excluding crustaceans, which are not insects.

Its claws and shell; it also uses its tentacles to feel for possible dangerous situations

once in a wile they shed maybe every4 months they always need bigger shells they live up to 2 and a half years or more if it is a healthy crab you should clean there tank/cage or whatever it is in and every couple days so keep your crab healthy

dua crustashons what do thay tech u these days so rite this down

It takes a Maine Lobster about six years to grow to weigh one pound.

Actually thats a question of the evolution. A fish that lives near by the sea can say "aw, I don't want to stay here, I go to the deep sea". Just because of factors like the sunlight or something like that they coulnd't live there. They adapt during many generation, and adapt slowly to the new circumstances. That's the same with a fish that lives in the deep sea. If you bring him up, and my not survive, because he can't stand for example the pressure. It's actually a question of time and developement.

not really because its on ground (ghost shrimp) and betta or beta eggs are on top

Yes, It is called molting. Crabs do it too. They loose their shell and are soft and it takes up to 10 days for the new shell to harden. * yes they can

Crayfish can sense changes in water pressure. They can also see to a limited extent. Additionally, they have two sets (pairs) of antennae that are sense organs. A link can be found below.

undercooked shellfish can be dangerous to eat.

Bad idea. If you've eaten sushi, you'll have noticed that they never serve uncooked shrimp. Lobster and shrimp are very similar.

While clams and oysters are often eaten raw, even they have a risk...they are known to carry what is called the "Norwalk Virus".

From the New England Journal of Medicine: 'Eating poorly cooked shellfish is currently a high-risk venture at best.''

It is hard for me to imagine why anyone would even attempt to eat something like under or un-cooked lobster or shrimp. The consistency would be like rubber. I don't even know if it's possible to chew into reasonable sizes to swallow...it would have to be cut up into small pieces and swallowed whole like a raw clam or oyster.

Indian Ocean and Pacific Ocean.

I dont know the answer and has no friends to ask.
