It depends how long it was refrigerated for. Crab is a meat that deteriorates very quickly after death, and should be eaten promptly, preferably the same day. The fact that the crab died in the fridge doesn't, in itself, make it bad to eat: if you were refrigerated naked, you'd die too in due course, so it was probably the refrigeration, combined with the stress the animal was placed under being caught, stored, transported, stored, transported again and stored again, that killed it.
You might want to think about the feelings of the crabs and try to eat them very soon after you buy them. Imagine how you'd feel being taken away from the only place you'd ever known, and the only place you can thrive, having your limbs tied together with rubber bands so you can't move them or fight back, being stacked up like wood with a whole lot of other crabs, most of whom you'd never met, and taken to places where they sit you on ice until they stick you in a plastic bag and shove you in a very cold fridge. And all this a very long way from the beautiful fresh ocean that you love so much ...
yes
my red flag,a dead crab and a blue burning flag
No....
If there is a STRONG fishy odor coming from the crab it means that he is dead.
It tears away the meat of a dead fish or what other dead thing that is in hte water with its claws, then inserts it in it mouth. His mouth lis located in the front of the shell between his eyes.
Well this sort of crab (the camouflage crab) I've researched it and it scavenge's all the dead particles in the water
Blue crabs usually eat clams, oysters, and mussels though they prefer freshly dead or freshly caught food. They do not eat barnacles but they are often found on the crab.
probely its dead or not
A dead mammal
not possible
Any dead creature in the water will putrefy and the resultant putrefaction will kill any fish in that water. So yes the dead crab will kill the Betta eventually.
All crabs look dead and are buried because they do not want to be eaten by another crab. So that's why they usually bury themselves to molt.
