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.
