I bought a whole cooked crab from the market. Is any part of it poisonous?!

Found this info for you:

Not all Crabs have edible meat in both the bodies and the claws. Dungeness Crabs and Blue Crabs are two examples of Crabs that do. To open a cooked Blue Crab or Dungeness Crab, or other type of Crab that has edible body meat, break off and set aside all the limbs, flip it upside down, and use a knife to pry off the shell in the centre of its bottom (called the "apron" flap.) Turn it right side up, lift off the top shell. Discard both shells, of course (or, if you are doing this in the kitchen, you can freeze them for making a stock later.) You will see a membrane covering the crabmeat, and on top of that some body parts (lungs and other things.) The grey, furry-looking things are the lungs (sometimes called "dead men's fingers".) The stomach is a grey sack just below the head. Scrape the lungs and stomach off, along with other innards and discard (they are not poisonous, but they are indigestible.) Then pull the halves apart, remove the gills and take out the dark meat. There's a bony bit in the centre. Crack the legs and the claws, and use a skewer to get the white meat out of them.

Alaska King Crab

Alaska King Crabs gave edible meat in claws and legs. Break off the claws and legs. Use your knife handle to crack them open so you can get at the meat inside them. Discard the body.

Stone Crabs

Stone Crabs have edible meat in their claws only. Break off the claws. Use your knife handle to crack them open so you can get at the meat inside them. Discard the body and legs.

Lump Crabmeat

From any Crab, large pieces of Crab that can be used for "presentation", such as in salads or pastas.

Backfin Crabmeat

Smaller, broken flakes or chunks of Crab meat that can be used in sauces or Crab cakes.

Crab Mustard

Many people love the strong-tasting, yellow stuff inside a Crab. It is a gland that branches out on both sides of the Crab's stomach to function as its liver and pancreas. In areas where the water may be doubtful, it's best not to eat this, as part of its function is to filter impurities, so any chemical contaminants will be concentrated in the mustard.

Still, aficionados gauge their entire cooking of the Crab on what state they want the mustard in -- neither hard nor runny, they feel it is best cooked just until it is like a soft-boiled egg

Are you trying to talk code about an STD slapper?

If so, the answer is yes, crabs are dangerous especially to the male species.

Well since we have cleared up that you are not talking in code,

The answer is no, it's all fine, the legs are the best part and it tastes nice with teriyaki sauce.

This is too Les: Gee, I am sure she appreciates the novel of an answer you put together, that is some good burning the oil reading for the next year you slapper.

The legs are fine.
If you crack into the body, you may find a green clump that is not supposed to be eaten.
Apparently it tastes awful, but as far as being poisonous, I have not heard that.
I have seen the green thing, and trust me, it does not look very appetizing.
Enjoy!

Poisonious. No. You're friend is uninformed.

I think they are safe.
But tell your friend that they are DEADLY poisonous.
More for you and me....

i'm not sure, you may want to test it out on someone first and see what transpires by morning!!!
