Crabs
Crabs are crustaceans living in any of the world's oceans, in fresh water, or on land, covered with a thick exoskeleton and armed with a single pair of claws. Many other animals with similar names – such as hermit crabs, king crabs, porcelain crabs,horseshoe crabs and crab lice – are not true crabs.
Crabs have a massive amount of ganglia, which can also be identified as the “brain.” They also have another mass of ganglia that passes down their body. Crabs don’t have a true brain but ganglia which are in control of all of their body functions. In other worlds, crabs have no brain, but instead a compressed group of ganglia that communicate when they touch each other. This works just as efficiently as humans nervous systems while taking up less space.
