This may sound like a strange question but.... Do crabs have blood? I've killed and cleaned plenty but no blood. They pinch me and i have blood. Fish have blood why not crabs? What do they have?


Thanks!

Got this off a google search, as I too did not know the answer to the question:

Crab blood is blue because it contains hemocyanin instead of hemoglobin. Hemocyanin contains copper, which gives the blood a clear, blue-grey color instead of the red color produced when oxygen binds to iron in hemoglobin

Crab blood is the white stuff you see all over the crabs after cooking.

I don't know if it is true or not, but I was told by a crabber years ago that a crab can loose a claw in the basket fighting and bleed to death.  Something to do with where the joint of the claw is broken.  At some point if broken it could grow back and at another point in the joint it can't and will bleed to death.
Any truth in this?

They can also get bit and bleed to death, this is more common in Jumbo's.. The blood can also stain or even eat the paint off if left to dry, for several days..

The information contained within the link is why I fist visited this site, it's so much more than a forum. Heads and shoulders above any other crabbing site I've visited in providing useful information.

Unless I am missing it, I didn't see a link anywhere here on the forum to the INFO. (except in Steve's post)  I did see a link on the INFO for the forum.

The link is a little hard to find. Cause it is assumed that people reach the Forum via the Info Site.  However, now with search engines like Google, most find the forum via a search for something Blue Crab related.  The search engines rank forum topics above other site pages. (Unless it is a very large text page. Then there are all kinds of definers the engines use.  Big long subject.)

Could be because 80% of them already know it all and only visit the forum to let the rest of us know it!
