Will a crab die out of water?
Well, the water has oxygen in the water so yes, the blue creek crab can live under water forever IF it has too. It usually goes up for oxygen, but the oxygen in the water is a secondary source.

Why is crab's blood white?
they do not have red blood cells/corpuscles like other animals. there is one variety of crab which has blue blood called Horseshoe crab, which they use it for medicinal purpose. Woodlice along with most other crustaceans including the horseshoe crab have the compound haemocyanin in their blood. Haemocycanin carries oxygen in the same way that haemoglobin does in mammals. Haemocycanin contains a copper atom instead of the iron atom found in haemogobin. The blood is pale blue when it is carrying oxygen and colourless when it is not carrying oxygen. hope this will solve your problems. hannah

How does a crab breathe on land?
Crabs need oxygen, just like we do, but instead of using lungs inside the body they use gills outside the body to obtain it.The mouthparts are visible on the underside of a crab. The gills through which the animal obtains oxygen cannot be seen. They are soft structures under the side of the shell.Their shells help to trap water near their gills so that they can still breathe the oxygen .
