fish have scales and crabs have a shell
Neither. It is not a vertebrate, so it cannot be either. A crab is a crustacean.
A shell provides protection and shelter for a hermit crab, which uses it as its home. The hermit crab carries the shell on its back and can move to a larger one as it grows. This symbiotic relationship benefits both the hermit crab and the shell.
No, a crab on a jellyfish would not be considered commensalism. Commensalism is a type of symbiotic relationship where one organism benefits without affecting the other organism. In this case, the crab is potentially benefiting by using the jellyfish for protection, while the presence of the crab may have negative effects on the jellyfish, making it more of a parasitic relationship.
Cod and pollack are both widely harvested and consumed species of fish. Unfortunately, there are no widely accepted rules used to differentiate one species from the other.
Most real and pure crab meat is truly zero carb food. Beware of artificial crabmeat, however, as sugar is used to make it taste like crab meat. It also seems that dungeonous/dungeness crab has some carb count so a low-carber will want to avoid that in any large amount and avoid the artificial crabmeat completely. http://www.carb-counter.org/fish/search/%20crab/1500 http://www.carb-counter.net/fish-shelfish

They are the same name for Birgus latro, the coconut crab.
an octopus has a squishy outer layer and a crab has a hard shell to protect it. the crab has claws to catch its food and an octopus has suckers to latch on to its prey. an octopus can also squeeze into really small spaces because it can move its skin and shrinks down to size. that is the difference between a crab and an octopus.
